Abstract
A cleaning device for an electrophotographic apparatus including an image carrier has a cleaning blade with an edge slidably contracting with an image carrier to remove foreign matter remaining on a surface of the image carrier. A lubricant including indefinite-form lubricant particles is applied to zones on the edges of the cleaning blade near both longitudinal ends of the cleaning blade and a lubricant including spherical lubricant particles is applied to a zone on the edge of the cleaning blade between the zones to which the lubricant including indefinite-form lubricant particles has been applied. A process cartridge includes the cleaning device, and an image forming apparatus incorporates the process cartridge.
