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.
