Abstract
An image forming apparatus includes a body, an intermediate transfer assembly, a secondary transfer assembly, and a drive motor. The intermediate transfer assembly is held by the body and includes an intermediate transferor. The secondary transfer assembly is held by the intermediate transfer assembly and includes a secondary transfer assembly and a cam. The secondary transferor assembly includes a secondary transferor rotatably held by the secondary transfer assembly. The secondary transferor presses the intermediate transferor. The cam contacts the secondary transferor assembly and adjusts a contact pressure of the secondary transferor against the intermediate transferor. The drive motor is held by the body and rotates the cam.
Claims11
An image forming apparatus comprising:
- a body;
- an intermediate transfer assembly held by the body, the intermediate transfer assembly including an intermediate transferor;
- a secondary transfer assembly held by the intermediate transfer assembly, the secondary transfer assembly including:
- a secondary transferor assembly including a secondary transferor rotatably held by the secondary transfer assembly, the secondary transferor to press the intermediate transferor;
- and
- a cam contacting the secondary transferor assembly, the cam to adjust a contact pressure of the secondary transferor against the intermediate transferor;
- and
- a drive motor held by the body and to rotate the cam;
- a transmission to transmit a driving force of the drive motor to the cam;
- and
- a conveyor held by the body and to convey a sheet in a conveyance direction,
- wherein the secondary transfer assembly is detachably attachable to the intermediate transfer assembly, and
- the conveyor is to:
- hold the secondary transfer assembly detached from the intermediate transfer assembly;
- be pullable from the body in a width direction orthogonal to the conveyance direction;
- and
- hold the drive motor and at least a part of the transmission.
An image forming apparatus, comprising:
- a body;
- an intermediate transfer assembly held by the body, the intermediate transfer assembly including an intermediate transferor;
- a secondary transfer assembly held by the intermediate transfer assembly, the secondary transfer assembly including:
- a secondary transferor assembly including a secondary transferor rotatably held by the secondary transfer assembly, the secondary transferor to press the intermediate transferor;
- and
- a cam contacting the secondary transferor assembly, the cam to adjust a contact pressure of the secondary transferor against the intermediate transferor;
- and
- a drive motor held by the body and to rotate the cam;
- a sensor to detect a rotation amount of the cam;
- and
- circuitry to control the drive motor based on the rotation amount detected by the sensor.
