Abstract
An electrophotographic image forming apparatus which sequentially performs charging, exposure, development, transfer and cleaning on each surface portion of a photoreceptor during rotation includes a cleaning blade configured to scrape off toner from the surface of the photoreceptor, a detecting unit configured to detect a rotation angle of the photoreceptor, and a control unit configured to control each of a start process and an end process of rotation of the photoreceptor. The control unit is also configured to control charging, development and transfer of the photoreceptor. In the end process, the control unit estimates a position of a surface portion of the photoreceptor, at which a charged state caused by a peeling discharge remains even after the stop of the photoreceptor, from the rotation angle from the time of start of deceleration of the photoreceptor to the time of stop of the photoreceptor, and adjusts parameters necessary for the next start process or end process.
