Abstract
An electrophotographic photoreceptor is disclosed, which comprises an electrically conductive substrate having formed thereon at least a charge generating layer and a charge transporting layer, wherein said charge generating layer is formed using a dispersed coating liquid prepared by mechanically grinding a perylene pigment and dispersing the ground perylene pigment in water, an alcohol series solvent, or an acetic acid ester solvent. A process of producing the photoreceptor is also disclosed. The electrophotographic photoreceptor provides a long pot life and stabilized dispersibility and electric characteristics.
Claims15
An electrophotographic photoreceptor comprising an electrically conductive substrate having formed thereon at least a charge generating layer and a charge transporting layer, wherein said charge generating layer is formed using a dispersed coating liquid prepared by mechanically grinding a perylene pigment and dispersing the ground perylene pigment in water, an alcohol series solvent, or an acetic acid ester solvent, said ground perylene pigment having strong diffraction peaks at about 6.2.degree., 12.3.degree. and 26.6.degree. to 26.9.degree. of the Bragg angle (2.theta..+-.0.2.degree.).
A process of producing an electrophotographic photoreceptor composed of an electrically conductive substrate having formed thereon at least a charge generating layer and a charge transporting layer using a coating liquid for the charge generating layer and a coating liquid for the charge transporting layer, which comprises forming said charge generating layer using a dispersed coating liquid obtained by mechanically grinding a perylene pigment and dispersing the ground pigment in water, or n-butyl acetate.
A process of producing an electrophotographic photoreceptor comprising forming a charge generating layer by applying a coating liquid comprising perylene pigment having strong diffraction peaks at about 6.2.degree., 12.3.degree. and 26.6.degree. to 26.9.degree. of the Bragg angle (2.theta..+-.0.2.degree.) dispersed in water, an alcohol series solvent, or an acetic acid series solvent.
