    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:

    wherein R₁ 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.
