Abstract
An electrophotographic imaging member is improved in light shock resistance by including in the charge transport layer a light shock resisting additive of triethanolamine, morpholine, an imidazole or mixtures thereof. The imaging member preferably has a charge generating layer containing hydroxygallium phthalocyanine, alkoxygallium phthalocyanine and mixtures thereof as the photogenerating particles. The method of rendering an imaging member including such a charge generating layer acceptably resistant to light shock includes forming a charge transport layer in association with the charge generating layer to contain the light shock resisting additive of triethanolamine, morpholine, an imidazole or mixtures thereof.
