Abstract
The invention relates to a multilayer type electrophotographic photoreceptor comprising: a conductive support; and, on the conductive support, a charge generation layer containing a hydroxygallium phthalocyanine pigment and a charge transport layer, wherein the content of α-chloronaphthalene in hydroxygallium phthalocyanine pigment in the charge generation layer is in a range of 0 ng/cm2 to 0.1 ng/cm2, the charge transport layer contains a non-halogen organic solvent having a boiling point of 140° C. or more, and the content of the non-halogen organic solvent having a boiling point of 140° C. or more is in a range of 0.1 μg/cm2 to 5 μg/cm2.
