An image forming apparatus includes a photosensitive drum, an image forming unit including an optical scanning device, a cleaning mechanism configured to clean a transparent window of the optical scanning device, and a control unit configured to cause the cleaning mechanism to perform a cleaning operation on the transparent window. The number of pages on which image formation is allowed to be performed for recording sheets in a period between cleaning operations performed by the cleaning mechanism is smaller in a case where image formation is performed on recording sheets in which the amount of generation of paper dust is large than in a case where image formation is performed on recording sheets in which the amount of generation of paper dust is small.
