ABSTRACT:
The present invention provides a charged member which has no reduction in the amount of electrostatic charge at high temperature and high humidity and no extreme increase in the amount of electrostatic charge at low temperature and low humidity, improves the adhesion force between a charged member and a coating layer, prevents deterioration of developer through peeling of the coating layer. It provides excellent durability without deterioration of toner through adhering of a toner to the carrier. More particularly, a carrier for electrophotography and a sleeve for electrostatic development which use as a coating material a high-molecular compound containing as an essential component the first monomer represented by the following general formula (1) and/or (2), the second monomer represented by the following general formula (3) and/or (4) and a coupling agent containing a vinyl group are provided.
