DEVELOPMENT MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHY DEVICE

摘要

A high-grade development member is provided that exhibits excellent deformation recovery properties at high temperatures and filming resistance properties at low temperatures. The development member of the present invention comprises an axial core body, an elastic layer that is formed on the outer peripheral surface of the axial core body, and a surface layer that covers the outer peripheral surface of the elastic layer. In order to provide both flexibility that makes it possible to minimize filming of toner and elasticity that makes it possible to minimize the occurrence of permanent compression set, the surface layer contains a first resin and a second resin. The first resin comprises a specific structure between two adjacent urethane bonds. The second resin is an acrylic resin having a specific structure.
