Abstract

PURPOSE:To prevent toner leaking out from a casing, by providing a sealing magnet closely and countering to the surface of a toner image carrier and providing the magnetic fine particles absorbed magnetically in a magnet brush shape to the sealing magnet. CONSTITUTION:A cleaning device CL is provided countering to a surface of an electrophotographic receptor drum 1 which is rotated and driven in the state in which residual toner T0 is stuck on its surface. A sealing magnet 23 is provided in the axial direction of the drum 1 at a magnet setting plate 22 of the cleaning device CL. The magnetic fine particles 24 is absorbed magnetically in a magnet brush shape to the surface countering to the drum 1 of the magnet 23, and by this magnetic fine particles 24, a magnetic brush for preventing leakage of toner is formed.
