摘要： An image forming apparatus includes a heating device, a rotator, and a blade. The heating device includes a heater extending in a direction orthogonal to a conveyance direction of a recording medium. The heater includes a heat generator and generates a larger heat amount at one end than at a center. The blade includes a rubbing portion extending in the direction. Both ends of the rubbing portion face both ends of the heater. The rotator and the blade are configured such that a friction force between the rotator and one end of the rubbing portion is smaller than a friction force between the rotator and the center of the rubbing portion in the direction.

摘要： An image forming apparatus includes an image bearer; a toner image forming device; an intermediate transferor; a primary transfer power source; a secondary transfer nip forming device; and a secondary transfer power source to output a secondary transfer bias. One of two peak values of the secondary transfer bias is a transfer peak value to provide a greater transfer-directional force to move toner from the intermediate transferor toward the recording medium in the secondary transfer nip. An absolute value of the transfer peak value is greater than an absolute value of the primary transfer bias.

摘要： 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.
