Abstract
A charging member includes a conductive support and a conductive elastic layer on the conductive support. The conductive elastic layer is made of a crosslinked product of a rubber composition containing a ternary epichlorohydrin rubber that is a copolymer of epichlorohydrin, an alkylene oxide, and allyl glycidyl ether; 4,4'-dithiodimorpholine; and a vulcanization accelerator that is a metal salt in an amount corresponding to 0.003 to 0.04 mol of metal per 100 g of the ternary epichlorohydrin rubber. The conductive elastic layer has a compression set of 20% or less.
