Abstract
A cleaning blade includes a supporting member, and a tabular elastic member. One end portion of the elastic member is fixed to the supporting member, and the other end portion is a free end portion whose tip edge is to be contacted with a member to be cleaned while rubbing the surface to remove a residual material therefrom. The tip portion of the free end portion of the elastic member ranging in length from 0 to 500 μm from the tip surface thereof includes at least a cured material of a curable compound and an elastic material of the elastic member. The elastic member satisfies the relationship, 0.05(%)≦[(tM−tA)/tA]×100≦2%, wherein tM represents the maximum thickness of the tip portion of the elastic member, and tA represents the average thickness of the rear portion of the free end portion of the elastic member.
