A wiper blade comprising a body made of an elastomeric material; and a surface coating layer positioned on a surface of the body and comprising a fluorine-containing resin having hydroxyl groups in the molecules thereof and a hardening agent having reactivity with the hydroxyl groups and optionally a solid lubricant. The surface coating layer is formed only on both side surfaces of the body. Thus, the wiper blade has a high degree of flexibility and restoring property; a high degree of durability; and judders in a slight extent when it slides on a glass surface in contact therewith; a high wiping performance; and maintains its wiping performance for a long time.

An object is to provide sheet feed members for use e.g. in a copying machine which make it possible to reduce the size of the copier and increase its operating speed, while satisfying all the other requirements expected for sheet feed members of this type. The sheet feed members are formed from a fluorocarbon resin.

A stripping finger, for use in an electrophotographic apparatus, formed by molding a glass polymer consisting of phosphate glass and resin. The stripping finger does not attack the peripheral surface of a roller of the electrophotographic apparatus. The material of the stripping finger can be molded precisely by injection molding; has a sufficient degree of heat load resistance, heat deformation property, and heat fatigue resistance; and is capable of maintaining the original shape of its tip.
