An image forming apparatus includes a photosensitive drum, a charging member, a developing member, a transfer member, a brush, a drive unit, a control unit, and a memory. The charging member charges a surface of the photosensitive drum at a charging portion. The transfer member comes into contact with the photosensitive drum to form a transfer portion. The drive unit rotatably drive the photosensitive drum. The control unit controls the drive unit to perform an image forming operation. The memory stores information about the image forming operation. In a case where the image forming operation is performed and a non-image forming operation is performed after the image forming operation, the control unit performs control such that a switching operation for stopping the photosensitive drum after the photosensitive drum is driven and re-driving the photosensitive drum is performed a plurality of times based on the information about the image forming operation.
