ABSTRACT:
An electrophotographing apparatus with a reusable toner system includes a photosensitive member capable of bearing toner thereon, a latent image forming unit for forming a latent image on the photosensitive member, a developing unit for developing the latent image with toner as a toner image, a transfer unit for transferring the toner image formed on the photosensitive member onto a transfer material at a transfer position, and a collection unit for collecting the toner from a surface of the photosensitive member after the surface passes through the transfer position. The collection unit includes a rotary member rotated while contacting the surface of the photosensitive member at a contact position. The rotary member is rotated in a direction opposite to a shifting direction of the photosensitive member at the contact position in such a manner that the relative speed of the rotary member with respect to the surface of the photosensitive member at the contact position becomes 110% or more of a shifting speed of the surface of the photosensitive member. The apparatus also includes a toner convey unit for conveying the toner collected by the collection unit to the developing unit so that the latent image formed on the photosensitive member can be developed by the toner collected by the collection unit.
