Claims

[Scope of utility model registration request]

In an electrophotographic apparatus equipped with a developing device in which rollers with an outer diameter larger than the outer diameter of the developing sleeve are disposed on both sides of the developing sleeve so as to be on a concentric axis with the developing sleeve and in contact with the photoreceptor, a brush-like member is attached to the developing sleeve. An electrophotographic apparatus characterized in that the electrophotographic apparatus is disposed at an end position of the photoreceptor inside the roller and outside the printing area so as to slide on the surface of the photoreceptor in a positional relationship parallel to the paper running direction.
