Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To provide an electrifying member, capable of reducing energy consumption at a manufacturing process capable of being recycled and without causing any failure such as a defective image. SOLUTION: A semiconductive elastic body layer 202 is formed on a conductive supporting body 201, and a non-adhesive protective layer 203 is formed on it at an electrifying roller for an image forming device. The material of the elastic layer 202 is thermo-plastic elastomer in which an ion conductive material is dispersed. The protective 203 consists of a resin where conductive particles are dispersed, and is formed into a laminated structure, where the volume resistivity is gradually raised from an inner layer side to an outer layer side. The elastic body layer is formed by coating the conductive supporting body with a composition, where perchloric acid lithium is mixed with the thermoplastic elastomer incorporating a polyester component by extrusion molding.  Also, the protective layer is formed into a four-layer laminated structure by the use of a coating material consisting of a polyvinylbutyral resin, an isocyanate curing agent, carbon black (volume resistivity conditioner) and toluene.
