Abstract: Disclosed is a photosensitive drum including: a cylindrical base body with a photosensitive layer formed on the outer peripheral surface thereof; and flanges respectively provided on both end surfaces of the cylindrical base body, the flanges being rotatably supported for rotatably supporting the photosensitive drum; wherein the cylindrical base body is molded from a conductive resin, and one of the flanges is molded from the conductive resin integrally with the cylindrical base body. The photosensitive drum, which contributes to a reduction in manufacturing cost by simplifying the manufacturing process and to improvement in reliability, is provided.

Abstract: A compound resin wheel with two or more moldings integrated to form the resin wheel, wherein at least one of the two or more moldings made of a long fiber reinforced thermoplastic resin, the other molding or moldings made of metal and/or FRP.

Abstract: A resin wheel of a one piece wheel type comprising a rim and a disk molded integrally, in which a portion between an axle hole of the disk and the rim is in a form of a blind plate with no holes, and the wheel is formed by injection molding or injection compression molding of a fiber-reinforced thermoplastic resin. A resin wheel of a one piece wheel type comprising a rim and a disk molded integrally, in which a portion between an axle hole of the disk and the rim is in the form of a blind plate with no holes, excepting for bolt holes and the wheel is formed by injection molding or injection compression molding of a fiber-reinforced thermoplastic resin.

Abstract: A resin wheel consisting of two or more molded parts coupled together. The parts are molded separately and have threaded portions. Then, the threaded portion of one molded part is screwed into the threaded portion of the other molded part so that the parts are fitted and coupled together.
