Abstract
A cleaning member for rubbing and removing toner having a shape coefficient SF of 10 to 150 remaining on a member to be cleaned in an electrophotographic apparatus. The cleaning member has an elastic blade, which has a 200 kg/cm or greater value or breaks a tensile strength of 300% elongation and a hardness of (JIS A) 60° to 80°. A blade supporting member causes the elastic blade to abut in a counter direction against the photosensitive member, which moves endlessly to rub and remove toner remaining on the photosensitive member after a transfer process, wherein the elastic blade abuts against a surface of a photosensitive member at an abutment pressure of a 55 gf/cm or greater without an inroad amount of the elastic blade into said photosensitive member exceeding 1.6 mm.
