Abstract
An electrophotographic photoconductor includes a phosphinate additive in a photosensitive film that improves the stability of the coating liquid for the photosensitive film. The electrophotographic photoconductor includes an electrically conductive substrate and a photosensitive film on the substrate. The photosensitive film contains a charge generation agent and a phosphinate compound. The photoconductor may be of either a monolayer or a laminate construction. In the case of a laminate type photoconductor, the phosphinate compound is incorporated into the charge transport layer. A method of making an electrophotographic photoconductor adds a phosphinate additive to the coating liquid for a photosensitive film to improve stability of the coating liquid. The method involves producing a coating liquid containing a phosphinate compound and coating a conductive substrate with the coating liquid to form a photosensitive film.
