Abstract
A control device to control an image forming apparatus including a rotatable image bearing member, a transfer device that transfers a toner image from the image bearing member to a transfer material by applying a transfer bias, a cleaning device that removes a residual toner from the image bearing member by a cleaning blade, and an image bearing member drive motor that rotates in forward and reverse direction to drive the image bearing member to rotate. The control device controls the image bearing member drive motor to rotate in the reverse direction to brake the image bearing member and then rotate the image bearing member in the reverse direction time after controlling the transfer device to stop application of the transfer bias, and controls the image bearing member drive motor to stop rotating the image bearing member after the image bearing member starts rotating in the reverse direction.
