Sound deadening member for electrophotographic photoreceptor and electrophotographic photoreceptor using the same

A sound deadening member for electrophotographic photoreceptor molded from a thermoplastic resin composition, the composition comprising:

• at least about 10 parts by weight of a copolymer (A) having a glass transition point of at least about 40° C., the copolymer (A) comprising from about 10 to 90% by weight of an acrylic acid ester monomer and/or a methacrylic acid ester monomer and from about 90 to 10% by weight of other monomer;
• not more than about 90 parts by weight of a styrene-base resin (B), the sum total of the copolymer (A) and the styrene-base resin (B) being 100 parts by weight;
• and
• wherein the sound deadening member is on a first side of a conductive support member, the conductive support member having a photosensitive layer formed on an opposite side of the conductive support member from the sound deadening member.
