摘要： An image forming apparatus includes a transferred body to which a toner image is transferred, a transfer device, a contact-separation device, and circuitry. The transfer device transfers the toner image from the transferred body onto a recording medium. The contact-separation device includes a motor and drives the motor to move the transfer device away from or into contact with the transferred body. The circuitry causes the contact-separation device to move the transfer device away from or into contact with the transferred body. The circuitry moves the transfer device away from the transferred body to a first position during standby and locates the transfer device at a second position that is closer to a contact position at which the transfer device is configured to contact the transferred body than the first position in an interval between the recording medium and a succeeding recording medium.

摘要： A material conveyor, included in a transfer device of an image forming apparatus and configured to use position control of rotary bodies, includes a first rotary body and a second rotary body disposed opposing each other in an opposing region through which a material is conveyable, and a contact and separation device configured to cause at least a surface, of at least one of the first rotary body and the second rotary body to move, between a separated position and a contact position. The contact and separation device is configured to cause the at least the surface to move from the separated position to the contact position, at a first speed, and then to move at a second speed slower than the first speed. A method of position control includes moving at least the surface at different speeds or based on a distance relative to a threshold distance.
