Abstract
Charge blocking materials include a complex or salt of a film forming material containing at least one nitrogen-containing compound, such as an amino, an imino or a tertiary amine group, chelated to a metal ion or atom. The charge blocking materials may be used in a charge blocking layer of an electrophotographic imaging member. The charge blocking materials may be used with transparent conductive layers, for example, comprising cuprous iodide.
