Image-holding member, and electrophotographic apparatus, apparatus unit, and facsimile machine employing the same
 The present invention provides an image-holding member which comprises an electroconductive support and a resin layer formed on the support, wherein the surface layer of the image-holding member contains a copolymer having the structure units represented by the formulas [I] and [II]: ##STR1## where A is a linear, branched or cyclic alkylidene group of 1 to 10 carbon atoms, an aryl-substituted alkylidene group, arylene-dialkylidene group, --O--, --S--, --CO--, --SO--, or --SO.sub.2 --; and R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are respectively hydrogen, halogen, or an alkyl or alkenyl group of 1 to 4 carbons; ##STR2## where R.sub.5 is an alkylene or alkylidene group of 2 to 6 carbons; R.sub.6 and R.sub.7 are respectively an alkyl group of 1 to 3 carbons, a phenyl or substituted phenyl group; and n is an integer of from 1 to 200, and the copolymer containing the structure unit of the formula [II] in an amount of from 0.1 to 50% by weight Of the total weight of the copolymer.
