Claims

[Claims for Utility Model Registration] (1) In a cleaning device for an image forming apparatus that removes toner remaining on the surface of a photoconductor with a brush that has bristles on the surface of a rotating shaft, the surface of the rotating shaft has a plurality of 1. A cleaning device for an image forming apparatus, characterized in that a rotating shaft has a polygonal cross-sectional shape so as to have a flat or concave surface, and bristles are planted perpendicularly to each surface of the rotating shaft to constitute a brush. (2) In a cleaning device for an image forming apparatus that removes toner remaining on the surface of the photoreceptor with a brush with bristles on the surface of a rotating shaft or an endless belt-shaped brush with bristles on the surface of a belt, the toner remaining on the surface of the photoreceptor may be removed locally. A brush base material, which is made by planting hair perpendicularly to each local concave surface on the front side of a flexible sheet material whose back surface is flat and is formed by repeating concave surfaces, is wound around the surface around a rotating shaft. 1. A cleaning device for an image forming apparatus, characterized in that the brush base material is pasted on the surface of an endless belt, or the brush base materials themselves are connected in an endless manner to form an endless belt-like brush.
