DEVELOPMENT ROLLER AND IMAGE FORMING APPARATUS USING THE SAME

摘要

This invention provides a development roller and an image forming apparatus using the same, which can eliminate the need to provide a drying line in the process of forming a resin layer and can use a carbon-based electrically conductive agent in the resin layer for imparting electrical conductivity to the resin layer. A development roller (1) comprises a shaft member (2) formed of a hollow cylinder or solid cylinder of an electrically conductive agent-containing resin and a resin layer (4). The resin layer (4) is formed of an ultraviolet curing resin comprising a carbon-based electrically conductive agent and an ultraviolet light polymerization initiator. The maximum wavelength in an ultraviolet absorption wavelength band of the ultraviolet polymerization initiator is not less than 400 nm. The resin layer (4) may be formed of an electrically conductive agent-containing electron beam curing resin.
