ABSTRACT:
A plurality of cleaning blades are provided for removing remaining developer on an electrophotographic photosensitive body used for an image forming apparatus. The cleaning blades include an abutment portion that abuts on the electrophotographic photosensitive body, and lubricant including insulating particles and conductive particles coating the abutment portion. The particle size of each of the insulating particles at D50by a volume regarded as a reference lies in a range of 0.2 to 1.0 μm and the particle size of each of the conductive particles at D50by a volume regarded as a reference lies in a range of 0.4 to 4.0 μm, D50being defined by the integration of volumes of particles calculated from a smaller particle size side that reaches 50% relative to a total integration thereof.
