摘要： A transfer device includes a movable component, a moving assembly, a restrictor, and an operating member. The movable component moves toward and away from a latent image bearer unit. The moving assembly causes the movable component to move toward and away from the latent image bearer unit. The restrictor restricts the latent image bearer unit from detaching from an image forming apparatus. The operating member causes the moving assembly to move the movable component away from the latent image bearer unit and releases restriction of detachment of the latent image bearer unit from the image forming apparatus by the restrictor.

摘要： A drive device that drives a detachable unit detachably attached to an image forming apparatus includes a drive coupling, a rotary shaft, a relay member, a contact member, and a compression spring. The drive coupling contacts and separate from a driven coupling of the detachable unit along with movement of the detachable unit. The relay member transmits rotation force of the rotary shaft to the drive coupling to rotate together. The compression spring has an axial end contacting the contact member disposed away from the driven coupling from the relay member and another axial end contacting the relay member. The drive coupling includes an outer circumferential restrictor restricts radial movement of the compression spring. The relay member includes an inner circumferential restrictor restricts radial movement of the compression spring.

摘要： A rotating device includes a shaft member, a counterpart member, a bearing, and a retaining member. The counterpart member includes a shaft insertion portion into which the shaft member is inserted. The bearing is disposed in the shaft insertion portion and interposed between the counterpart member and the shaft member. The bearing causes the counterpart member and the shaft member to be rotatable relative to each other. The retaining member is disposed on an end portion of the shaft member on one side in an axial direction of the shaft member. The counterpart member includes an opposing portion closer to the end portion of the shaft member on the one side in the axial direction than the bearing. The opposing portion faces the retaining member in the axial direction.

摘要： A transfer device includes an intermediate transferor to rotate, primary transfer sections, a tension roller, a first movement mechanism, and a second movement mechanism. Each of the primary transfer sections includes a primary transferor. The tension roller stretches the intermediate transferor. The first movement mechanism causes the tension roller to move and change a position at which the tension roller stretches the intermediate transferor. The second movement mechanism causes the primary transferor of a primary transfer section to move to a contact position at which the primary transferor contacts a latent image bearer and a separation position at which the primary transferor is separated from the latent image bearer. The most-downstream primary transferor is movable between a contact position and a separation position. The first movement mechanism causes the tension roller to move to at least three positions at each of which the tension roller stretches the intermediate transferor.

摘要： A transfer device includes an intermediate transferor and primary transfer sections. The primary transfer sections each includes a primary transferor. The primary transfer sections include a most-upstream primary transfer section and a most-downstream primary transfer section. One of the primary transfer sections is a special-color primary transfer section switchable between the most-upstream primary transfer section and the most-downstream primary transfer section. The primary transferor of each of the most-upstream primary transfer section and the most-downstream primary transfer section is switchable between a contact position at which the primary transferor contacts the latent image bearer and a separation position at which the primary transferor is separated from the latent image bearer. With only the primary transferor of the special-color primary transfer section at the separation position, the primary transferor of any other primary transfer section than the special-color primary transfer section is arranged at the contact position to transfer an image.
