Patent ID: 8906586

Claim:
An electrophotographic photoreceptor, comprising: (i) a charge-generating material comprising a metal coordination phthalocyanine; (ii) a binder resin; and (iii) a photosensitive layer formed from a coating fluid comprising the charge-generating material (i), wherein a dispersing medium comprising particles having an average particle diameter in a range of from 10 μm to 100 μm, disperses the charge-generating material (i) in the coating fluid, wherein the metal coordination phthalocyanine comprises a phthalocyanine pigment and the phthalocyanine pigment in the coating fluid comprises primary particles and secondary aggregated particles, which have a 50% cumulative particle diameter (D50) of 0.13 μm or smaller and a 90% cumulative particle diameter (D90) of 0.25 μm or smaller, as determined by a dynamic light scattering method, wherein particles of the metal coordination phthalocyanine in the coating fluid have a dispersion index of about 1.41 to at most 2.51.
