Electrophotographic charge generating element containing primer layer

摘要

Electrophotographic charge generating elements comprise a solid electrolyte layer having improved image discrimination and layer adhesion. The solid electrolyte layer includes a complex of a silsesquioxane and a charge carrier, and is adhered to an underlying photoconductor layer using a primer layer that includes specific addition polymers. This primer layer has a resistivity of at least 1010 ohms/square and contains substantially no free ACTIVE moieties as defined herein. Such groups, when present in the primer layer, appear to reduce image discrimination.
