Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND IMAGE FORMATION APPARATUS
Document Type and Number:
Japanese Patent JP2023079591
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor which has a charge generating layer having little foreign matters and can suppress a transfer memory.SOLUTION: An electrophotographic photoreceptor includes a conductive substrate, and a photosensitive layer. The photosensitive layer includes a charge generating layer, and a charge transport layer. The charge generating layer contains a phthalocyanine pigment, and a first resin. A ratio of the mass of the phthalocyanine pigment to the mass of the first resin is larger than 2.0 and less than 3.5. A ratio A830/A783 of second absorbance A830 to first absorbance A783 of the charge generating layer is 0.97 or more and 1.10 or less. The first absorbance A783 is absorbance of the charge generating layer to first light having a wavelength of 783 nm. The second absorbance A830 is absorbance of the charge generating layer to second light having a wavelength of 830 nm.SELECTED DRAWING: Figure 1
