摘要： An electrophotographic sensitive medium and apparatus for use with this medium. The electrophotographic sensitive medium has an electroconductive support, a sensitive layer, and an intermediate layer interposed between the support and the sensitive layer. The intermediate layer material contains a polyamide grafted with a polymer or a copolymer, and the polymer of copolymer contains a unit component represented by the following general formula: ##STR1## wherein R.sub.1 is a hydrogen atom or a methyl group, Z is --O-- or --NH--, and A is an alkylene group having 1 to 6 carbon atoms.

摘要： An electrophotographic photosensitive member has a substrate, a photosensitive layer and an intermediate layer spaced between said substrate and said photosensitive layer. The intermediate layer contains a polyamide resin grafted with a polymer or a copolymer having a unit component expressed by the following general formula (I) ##STR1## wherein, R.sub.1 is hydrogen atom or a methyl group, each of R.sub.2 and R.sub.3 is a hydrogen atom, an alkyl group or an aryl group or R.sub.2 and R.sub.3 in combination is a residual group necessary for forming a heterocyclic compound containing N, R.sub.2 and R.sub.3 are the same or different from each other. Also disclosed are an electrophotographic apparatus having the photosensitive member, and a facsimile incorporating the electrophotographic apparatus.
