Image forming apparatus capable of adjusting a moving speed ratio
Abstract:
An image forming apparatus, includes: an intermediate transfer type image forming unit that primarily transfers a toner image formed on an electrophotographic photosensitive member to an intermediate transfer member and then secondarily transfers the toner image from the intermediate transfer member to a printing medium; and a control unit that controls a moving speed ratio ΔV represented by Expression 1 depending on a usage history of the electrophotographic photosensitive member, Δ ⁢ ⁢ v ⁡ [ % ] =  v 2 - v 1  v 1 × 100 ( 1 ) where V1 is a moving speed [mm/s] of a surface of the electrophotographic photosensitive member; and V2 is a moving speed [mm/s] of a surface of the intermediate transfer member in a moving direction of the surface of the electrophotographic photosensitive member, wherein the electrophotographic photosensitive member comprises a surface layer containing a curable resin on a surface facing to the intermediate transfer member.
