Abstract: PROBLEM TO BE SOLVED: To prevent an abnormal image by scraping and scattering about residual toner on a photoreceptor. SOLUTION: A toner scattering means 7 is provided in a case 10, and a scattering member constituted of an elastic member is arranged therein. The scattering members are provided and arranged so that the edge part abutting on the surface of the photoreceptor in the longitudinal direction of a belt-shaped plate may have an optional angle to the axial direction of the photoreceptor and adjacently arranged through space.
