PURPOSE: To obtain a cleaning blade which is formed of a material obtd. by randomly arranging fibrous materials over the entire part and is so constituted as to prevent the growth of flaws. CONSTITUTION: The cleaning blade 10 is formed of the elastomer material. The spacings 65 between the packing material fibers 60 over the entire part of the elastomer material are parted from the mutual packing material fibers 60 by as much as the smaller of either <=10 times the toner particle diameter or carrier bead diameter Dc. These packing material fibers 60 are the fibers 60 which are eventually arranged randomly over the entire part of the elastomer material, are short, a high in an aspect ratio (i.e., the ratio of another size to one size, like length to width) and are high in tensile strength. Fibers of glass, carbon, graphite, minerals, nylon, polyester, polyurethane terephthalate, boron, silicon carbide, aramid, ceramic and metals are included in the satisfactory materials for the packing material fibers 60. |
