Abstract:
A toner conveying device conveys toner supplied from outside. The toner conveying device includes a housing, a plurality of toner acceptors, a plurality of legs, a bracket, and a vibration generator. The housing has a toner conveyance path inside. The toner acceptors are provided on the housing to accept toner supplied from outside and guide the toner to the toner conveyance path. The legs are fixed near the toner acceptors on the housing, respectively, and protrude outward from a side surface of the housing. The bracket is supported by each of the legs. The vibration generator is attached to the bracket.
Abstract:
An image forming apparatus includes a transfer belt rotating in a rotational direction, photosensitive drums, primary transferring parts, static eliminating parts and cleaning parts. The static eliminating part is arranged between the primary transferring part and the cleaning part, and includes a light guide body and a light source arranged at one end side of the light guide body. The static eliminating part irradiates upstream and downstream sides from the light guide body in the rotational direction with the static eliminating light. The image forming apparatus comprises a first light shading part and/or a second light shading part. The first/second light shading part is arranged between the photosensitive drum at a downstream/upstream side from the light guide body in the rotational direction and the light guide body to adjust pre-transfer/post-transfer static eliminating light quantity from the light guide body to the downstream/upstream side photosensitive drum.
Abstract:
A developing device includes a developing container, a developing roller, a regulating blade, a seal member, and a resin member. The regulating blade includes a mounting plate and a blade plate. The developing container has a facing part facing a step part due to thickness difference between the mounting plate and the blade plate. The seal member has a resin placement area, and is squeezed between the regulating blade and the facing part. The resin placement area is an area that penetrates the seal member and is surrounded by the seal member. The resin placement area overlaps the step part.
Abstract:
An image forming apparatus includes a photosensitive drum, an exposure device, a supporting member and a main adjustment member. The photosensitive drum is provided for each of colors forming a color image. The exposure device is configured to emit a laser light on each of the photosensitive drums to form an electrostatic latent image. The supporting member is configured to support end portions of rotation shafts of all the photosensitive drums. The main adjustment member is configured to shift the supporting member in a vertical plane to adjust a skew of the laser light.
Abstract:
A developing device contact and separation mechanism includes a monochrome operating member, a color operating member, and a rotating member that rotates among a first position for a non-operational state, a second position for color printing, and a third position for monochrome printing. At the first position, the rotating member moves the monochrome developing device to the separated position, via the monochrome operating member, and the color developing device to the separated position, via the color operating member. At the second position, the rotating member moves the monochrome developing device to the contacting position, via the monochrome operating member, and the color developing device to the contacting position, via the color operating member. At the third position, the rotating member moves the monochrome developing device to the contacting position, via the monochrome operating member, and the color developing device to the separated position, via the color operating member.
Abstract:
An image forming apparatus includes a groove, an exposure device and an adjustment member. In the groove, each of end portions of a rotation shaft of a photosensitive drum is inserted. The exposure device is configured to emit a laser light on the photosensitive drum to form an electrostatic latent image. An adjustment member is configured to shift each of the end portions of the rotation shaft to adjust a skew of the laser light.
Abstract:
An image forming apparatus includes a groove, an exposure device and an adjustment member. In the groove, a rotation shaft of a photosensitive drum is inserted. The exposure device is configured to emit a laser light on the photosensitive drum to form an electrostatic latent image. The adjustment member is configured to shift the rotation shaft vertically in the groove to adjust a skew of the laser light.
Abstract:
A developing device of the present disclosure includes a developing roller, a toner supply roller, a regulation blade, a casing, a toner receiving support member, a toner receiving member, a vibration generation unit, and a vibration inhibition member. The toner receiving support member is disposed in the casing so as to be opposed to the developing roller or the toner supply roller in an area between the regulation blade and an image carrier. The toner receiving member has a toner receiving surface that receives toner dropping from the developing roller, and is supported so as to be swingable about an end edge thereof on a toner supply roller side as a fulcrum. In a state where the toner receiving member is not vibrating, the vibration inhibition member is in contact with each of both end portions of the toner receiving surface in a longitudinal direction thereof.
Abstract:
The image forming apparatus includes an image carrier, a developing unit, and a housing. The developing unit includes a toner carrier, a development container, a circuit board, and a board retaining portion. The development container rotatably supports both end portions of a rotating shaft of the toner carrier, and contains developer and the toner carrier. The development container includes a protrusive support portion which protrudes from both end portions of an axial direction and which is pivotably supported by a retaining frame. The development container is pivoted on the protrusive support portion serving as a fulcrum, and the toner carrier is reciprocatively movable so as to come into contact with or separate farther from the image carrier. The board retaining portion is pivotably supported on a fulcrum given by a retention support portion coaxial with the protrusive support portion, and is independent of the reciprocative movement of the development container.
Abstract:
An image forming apparatus includes a groove, an exposure device and an adjustment member. In the groove, an end portion of a rotation shaft of a photosensitive drum is inserted. The exposure device is configured to emit a laser light on the photosensitive drum to form an electrostatic latent image. The adjustment member is configured to shift the end portion of the rotation shaft in a direction other than a vertical direction in the groove to adjust a skew of the laser light.
