Abstract:
1. An image forming apparatus comprising: a photosensitive member; a charging device configured to electrically charge said photosensitive member at a charging position; an exposure device configured to expose to light said photosensitive member charged by said charging device to form an electrostatic image on said photosensitive member; a developing device configured to develop the electrostatic image on said photosensitive member with toner to form a toner image, wherein said developing device includes a rotatable developing sleeve and effects development by rotating the developing sleeve; a first transfer device configured to transfer the toner image from said photosensitive member onto an intermediary transfer member at a transfer position; a second transfer device configured to transfer the toner image from the intermediary transfer member onto a recording material; a toner charging device, disposed upstream of said charging position and downstream of said transfer position with respect to a rotational direction of said photosensitive member, said toner charging device is contacting with said photosensitive member and configured to electrically charge, at a toner charging position, the toner remaining on said photosensitive member without being transferred; and a controller configured to control said charging device, said exposure device and said developing device so that a plurality of stripe-shaped electrostatic images are formed substantially in parallel with a longitudinal direction of said photosensitive member on a surface of said photosensitive member and are arranged in the rotational direction of said photosensitive member and so that toner deposited on said toner charging device is discharged to said photosensitive member when the plurality of stripe-shaped electrostatic images pass through said toner charging device in a state in which the rotation of said developing sleeve in stopped.
