Estimating the term…
An image forming apparatus that has a transfer device that includes an intermediate transfer belt that is tensioned by a plurality of support rollers, a secondary transfer roller that faces one of the support rollers via the intermediate transfer belt, a cam that adjust a pressing force that presses the intermediate transfer belt by the secondary transfer roller, a motor that drives the cam, and a conveyor that conveys a recording medium to a transfer nip formed between the intermediate transfer belt and the secondary transfer roller is provided with a controller that controls an operation of the motor. The controller executes first control of operating the motor with a constant torque and stopping the motor when a rotation angular speed of the motor is less than or equal to a first threshold and second control of operating the motor at a predetermined timing to adjust a transfer nip amount.
An image forming apparatus that has a transfer device that includes an intermediate transfer belt that is tensioned by a plurality of support rollers, a secondary transfer roller that faces one of said support rollers with said intermediate transfer belt interposed between said one of said support roller and said secondary transfer roller, a cam that can adjust a pressing force that presses said intermediate transfer belt by said secondary transfer roller, a motor that drives said cam, and a conveyor that conveys a recording medium to a transfer nip formed between said intermediate transfer belt and said secondary transfer roller, said image forming apparatus comprising:
A transfer method in an image forming apparatus that has a transfer device that includes an intermediate transfer belt that is tensioned by a plurality of support rollers, a secondary transfer roller that faces one of said support rollers with said intermediate transfer belt interposed between said one of said support roller and said secondary transfer roller, a cam that can adjust a pressing force that presses said intermediate transfer belt by said secondary transfer roller, a motor that drives said cam, a detector that detects a rotation angle of said motor, and a conveyor that conveys a recording medium to a transfer nip formed between said intermediate transfer belt and said secondary transfer roller, said transfer method comprising:
A non-transitory computer-readable storage medium storing a transfer control program operating in an image forming apparatus that has a transfer device that includes an intermediate transfer belt that is tensioned by a plurality of support rollers, a secondary transfer roller that faces one of said support rollers with said intermediate transfer belt interposed between said one of said support roller and said secondary transfer roller, a cam that can adjust a pressing force that presses said intermediate transfer belt by said secondary transfer roller, a motor that drives said cam, a detector that detects a rotation angle of said motor, a controller that controls an operation of said motor, and a conveyor that conveys a recording medium to a transfer nip formed between said intermediate transfer belt and said secondary transfer roller, said transfer control program causing said controller to perform:
