Abstract
An electrophotographic photoconductor has an intermediate layer formed between an electrically conductive substrate and photosensitive layer. The intermediate layer is made of a hardened film formed by hardening an amino resin with a catalyst comprising aromaticsulfonic acid, alicyclicsulfonic acid, a mixture thereof, or latent acid thereof to provide good image qualities without causing any troubles in the process of image formation.
