Abstract: A gripping mechanism includes a holder, a gripping roller, and a lever. The gripping roller is housed within the holder and grips an object between the roller and an inner surface of the holder. The lever releases gripping of the object by pushing the gripping roller upward. Preferably, the holder includes two plate sections which support a weight of the gripping roller. An opening is located between the two plate sections. The opening receives insertion of the object. One of the two plate sections is inclined relative to a vertical direction.

Abstract: An image carrier unit includes an image carrier including a cylindrical main body portion and a pair of flange portions attached to both ends of the main body portion, a first cleaning member that rotates in contact under a prescribed pressure with an outer circumferential surface of the main body portion, a unit frame that rotatably supports the image carrier and the first cleaning member, and an image carrier protective cover that includes a cover main body extending in an axial direction of the image carrier and a side surface portion that is disposed on one end side of the cover main body. On the side surface portion, an image carrier holding portion is formed that performs positioning of the image carrier with respect to the unit frame and releases a pressure contact state between the image carrier and the first cleaning member.

Abstract: A gripping mechanism (3) includes a gripping roller (32) and a holder (31) that houses the gripping roller (32). A gripped portion (42) of a first component (4) is gripped between an outer surface of the gripping roller (32) and an inner surface of the holder (31) through action of gravity acting on the gripping roller (32). Preferably, the gripping roller (32) includes a core (321) that is cylindrical or columnar in shape and a covering section (322) that is an elastic body covering a circumferential surface of the core (321). Preferably, the covering section (322) has a circumferential surface with a friction coefficient greater than a friction coefficient of the circumferential surface of the core (321).

Abstract: A gripping mechanism includes a holder, a gripping roller, and a downward pushing section. The holder houses the gripping roller. The downward pushing section pushes downward on an object gripped between the holder and the gripping roller. Preferably, the downward pushing section has a first downward pushing mechanism, a second downward pushing mechanism, and a third downward pushing mechanism. The first downward pushing mechanism protrudes from a ceiling surface among inner surfaces of the holder. The second downward pushing mechanism and the third downward pushing mechanism protrude from respective surfaces opposite to the object among outer surfaces of the holder.

Abstract: An image forming apparatus includes a photoconductor drum, a developing roller, a first shaft provided for one of the photoconductor drum and the developing roller, a second shaft provided for the other of the photoconductor drum and the developing roller, a first housing that supports the first shaft, a second housing that supports the second shaft, a cylindrical supporting member provided at an axial end portion of the first shaft of the first housing, and surrounding the first shaft without contact, and a first adjusting member fitted with an outer surface of the supporting member, and rotatable in a circumferential direction of the supporting member. An outer circumferential surface of the first adjusting member is formed in an arcuately curved shape, eccentric with respect to the supporting member, and located in contact with the second housing.

Abstract: A gripping mechanism includes an inclined surface, a rolling element, and a facing gripping part. The inclined surface is a surface inclined to a vertical direction. The rolling element freely rolls obliquely upward and downward on the inclined surface. The facing gripping part is arranged to face the inclined surface and forms an opening space with an end of the inclined surface, the opening space being narrower than a diameter of the rolling element. The rolling element includes: a core member forming a core of the rolling element; an annular member that is provided around the core member and has elasticity; and a plurality of ribs each of which is interposed between an outer periphery of the core member and an inner periphery of the annular member, and forms a gap between the core member and the annular member.
