Abstract
A composite metal phthalocyanine crystal particle is disclosed. In the composite metal phthalocyanine crystal particle, metal phthalocyanine compound A in an amount of at least 0.001 to less than 0.1 weight part is uniformly dispersed at the molecular level in 100 weight parts of metal phthalocyanine compound B which has a different chemical structure from said metal phthalocyanine compound A.
Claims10
An electrophotographic photoreceptor comprising a support and, provided thereon, a photosensitive layer containing composite metal phthalocyanine crystal particle wherein metal phthalocyanine compound A in an amount of at least 0.001 to less than 0.1 weight part is uniformly dispersed at the molecular level in 100 weight parts of a main metal phthalocyanine compound B which has a different chemical structure from said metal phthalocyanine compound A, said metal phthalocyanine compound A has an electron attractive group and said composite has a minimal amount of a metal phthalocyanine compound with an electron attractive group, said minimal amount being at least 0.001 to less than 0.1 weight parts based on 100 weight parts of said main compound.
A composite metal phthalocyanine crystal particle wherein metal phthalocyanine compound A in an amount of at least 0.001 to less than 0.1 weight part is uniformly dispersed at the molecular level in 100 weight parts of a main metal phthalocyanine compound B which has a different chemical structure from said metal phthalocyanine compound A inside said crystal particle, said metal phthalocyanine compound A has an electron attractive group and said composite has a minimal amount of a metal phthalocyanine compound with an electron attractive group, said minimal amount being at least 0.001 to less than 0.1 weight parts based on 100 weight parts of said main compound.
An electrophotographic photoreceptor comprising a support and, provided thereon, a photosensitive layer containing composite metal phthalocyanine crystal particle consisting essentially of metal phthalocyanine compound A and metal phthalocyanine compound B, wherein metal phthalocyanine compound A in an amount of at least 0.001 to less than 0.1 weight part is uniformly dispersed at the molecular level in 100 weight parts of metal phthalocyanine compound B which has a different chemical structure from said metal phthalocyanine compound A and said metal phthalocyanine compound A has an electron attractive group.
