Abstract

An image forming apparatus includes a rotatable photosensitive member, and a charging member for electrically charging the photosensitive member in contact or proximity to the photosensitive member. The charging member forms an upstream gap and a downstream gap between the photosensitive member and itself. In addition, a power source applies a DC voltage to the charging member, an irradiation unit irradiates with light a surface of the photosensitive member in the upstream gap, and a controller controls the irradiation of the light by the irradiation unit. The photosensitive member is movable at a first speed and a second speed slower than the first speed, and wherein the irradiation of the light is effected when the photosensitive member is moved at the first speed to effect image formation, and is not effected when the photosensitive member is moved at the second speed to effect the image formation.
