Abstract
An image forming apparatus includes: an image carrying member; a charging device; an exposure device; a developing device; a drive unit; a developing-voltage power supply; and a control unit. The developing device has a developer carrying member which is configured to carry a two-component developer containing a toner and a carrier. The developing-voltage power supply is configured to apply a developing voltage to the developer carrying member, the developing voltage being generated by superimposition of an AC voltage onto a DC voltage. The image forming apparatus has a first print mode in which an image carrying member is driven and rotated by a drive unit at a linear speed of 250 [mm/sec] or more. The image carrying member has a single organic-photosensitive layer as a photosensitive layer. The photosensitive layer has a layer thickness of 40 [μm] or more at start of use.
