Abstract:
An electrophotographic imaging member, comprising:an electrically conductive substrate;a charge transport layer that comprises a hole transport component;a charge generating layer that comprises organic photoconductive particles and said hole transport component;wherein the hole transport component forms a concentration gradient in the charge generating layer such that a lower concentration of the hole transport component is located furthest from the charge transport layer and a higher concentration of the hole transport component is located nearest the charge transport layer;wherein an amount of the hole transport component in the charge generating layer is effective to block migration of the hole transport component from the charge transport layer to the charge generating layer; andwherein the hole transport component is N,N'-diphenyl-N,N'-bis(3-methylpropyl)-(1,1'-biphenyl)-4,4'-diamine.
