CONDUCTIVE MEMBER, ELECTROPHOTOGRAPHIC APPARATUS, AND PROCESS CARTRIDGE

摘要

Provided is a conductive member which has a uniform electrical resistance that is not changed much due to processing conditions. This conductive member comprises a conductive supporting body and a conductive elastic layer. The elastic layer is a mixture containing an electron conductive agent and a binder polymer, or a cured product of the mixture; and the electron conductive agent contains carbon black that satisfies the following characteristics. (i) The average primary particle diameter is from 20 nm to 30 nm (inclusive). (ii) The DBP oil absorption is from 40 ml/100 g to 70 ml/100 g (inclusive), and the total amount of CO and CO2 generated by a hot gas generation analysis is from 0.30% by mass to 0.80% by mass (inclusive) based on the carbon black. (iii) The amount of SO2 generated by the hot gas generation analysis is 0.05% by mass or more based on the carbon black.
