An image forming apparatus includes a rotatable drum; a charging roller, contacting the drum, for electrically charging the drum; a developing device for developing a latent image formed on the drum into a developer image; and a cleaning device for removing a developer remaining on the drum after the developer image is transferred from the drum onto a developer image receiving member. The cleaning device includes a cleaning blade contacting the drum and having a fixed end and a free end which is located upstream of the fixed end with respect to a rotational direction of the drum. The image forming apparatus further includes a control device for controlling a rotating operation of the drum. The control device is capable of performing an operation for rotating the drum, in a direction identical to the rotational direction of the drum during image formation effected by rotating the drum, after a lapse, without next instruction of image formation, of a predetermined period from a stop of rotation of the drum once made after completion of the image formation. The predetermined period is longer with a larger number of sheets subjected to the image formation in an image forming job before the rotation of the drum is stopped.
