Abstract
An image forming apparatus includes a photosensitive member; a charging device, a developing device, a transfer device, and a controller. The controller is capable of executing an operation in a first mode in which an image forming operation is controlled so that an exposure start enable timing is set during movement of the photosensitive member through one full circumference from first passing, through an exposure position, of a region of the photosensitive member which has passed through a charging position, and executing an operation in a second mode in which an image forming operation is controlled so that the exposure start enable timing is set after the movement of the photosensitive member. On the basis of image information of the first sheet of an image forming job, the controller selects an executing mode from a plurality of modes including at least the first mode and the second mode.
