Abstract
A blade member, mountable onto an electrophotographic image forming apparatus, such as copier, printer, facsimile, word processor, and the like, for removing residual matter from an electrophotographic photosensitive member, includes an elastic blade one side surface of which is flat in a longitudinal direction thereof and the other side surface of which has a vertical portion perpendicular to an end surface of the elastic blade, and an inclined portion inclined with respect to the vertical portion, the inclined portion having a larger thickness than the vertical portion, and a support member for supporting the elastic blade. A thickness (f) of a portion of the elastic blade, which is engaged by the support member at a side of the one side surface, is greater than a thickness (g) of a portion of the elastic blade which is engaged by the support member at a side of the other side surface.
