Abstract: A cleaning device includes a plurality of cleaners. The plurality of cleaners includes at least a first cleaner, a second cleaner, and a third cleaner arranged next to each other in a traveling direction of a cleaning target. The first cleaner is disposed at an extreme upstream end of the traveling direction and supplied with a first voltage having a same polarity as a polarity of a normally-charged toner. The cleaners, other than the first cleaner, disposed downstream from the first cleaner, is supplied with a second voltage having a polarity opposite the polarity of the normally-charged toner.

Abstract: An image forming apparatus includes an image bearer on which a toner image is formed, an intermediate transfer belt onto which the toner image transferred from the image bearer, a secondary transfer member, a guide assembly, and a biasing device. The secondary transfer member meets the intermediate transfer belt to form a secondary transfer nip in which the toner image is transferred from the intermediate transfer belt onto a recording sheet. The guide assembly disposed upstream from the secondary transfer member in a transport direction of the recording sheet guides the recording sheet at a position lower than the secondary transfer nip such that a leading end of the recording sheet contacts the secondary transfer member before entering the secondary transfer nip. The biasing device biases the secondary transfer member to move the secondary transfer member in one of a direction of bias and a vertical direction.

Abstract: A cleaning device includes a cleaner, a plurality of cleaning sub-units, a sub-unit holder, a detachable transmission assembly, and a plurality of joint couplers. The cleaner scrapes off adhered material from a surface of a cleaning target while contacting the surface of the cleaning target. The cleaning sub-units each includes a holder to hold the cleaner and a drive-receive rotator to receive a driving force. The sub-unit holder holds the cleaning sub-units. The detachable transmission assembly includes a driving-force receive rotator to receive a driving force from an external unit and a plurality of drive transmission rotators to transmit the driving force received by the driving-force receive rotator to the drive-receive rotators of the cleaning sub-units. The joint couplers mounted on the drive-receive rotators and the drive transmission rotators couple the drive-receive rotators with the drive transmission rotators in a rotation axial direction.

Abstract: An image forming apparatus includes an image carrier, a toner-image forming unit, a transfer unit, a cleaner, a plurality of cylindrical transport path forming members, a falling transport path forming member, and a discharge port. The falling transport path forming member has through holes in a side wall thereof. A second end of each of the transport path forming members is inserted into a corresponding one of the through holes. The falling transport path forming member forms a falling transport path that causes toner ejected from an ejection port disposed in the second end to fall. The discharge port is disposed in a lower part of the falling transport path forming member to discharge the toner to a discharge destination. The second ends of the transport path forming members are disposed offset from each other in a horizontal direction on the side wall of the falling transport path forming member.

Abstract: A process cartridge includes an image bearer, a developer bearer, and a positioning member. The image bearer is rotatable. The developer bearer is rotatable and opposite to the image bearer. The positioning member determines an opposing distance between the image bearer and the developer bearer, and includes a fitting portion and a groove. A fitted portion of the image bearer rotatably fits to the fitting portion. The groove extends from a ceiling portion to a bottom portion. A shaft portion of the developer bearer is slidingly movable in the groove. The groove is formed such that the shaft portion of the developer bearer contacts the bottom portion and is supported by the bottom portion. The ceiling portion of the groove is open upward so that the shaft portion of the developer bearer is insertable to and removable from the groove.
