ELECTROPHOTOGRAPHIC PHOTORECEPTOR CONTAINING MIXTURE OF BISPHTHALOCYANINE-BASED COMPOUND AND PHTHALOCYANINE-BASED COMPOUND AND ELECTROPHOTOGRAPHIC IMAGING APPARATUS EMPLOYING THE ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

An electrophotographic photoreceptor includes an electrically conductive substrate, and a photosensitive layer formed on the electrically conductive substrate, in which the photosensitive layer includes a mixture of a bisphthalocyanine compound represented by a formula and a phthalocyanine compound represented by another formula. The mixture of the bisphthalocyanine compound represented by the formula and the phthalocyanine compound represented by the other formula has higher stability with respect to a transition of crystal type, crystal growth, and/or agglomeration in a photosensitive layer forming composition than a phthalocyanine-based charge generating material. Therefore, the electrophotographic photoreceptor including the mixture as a charge generating material has excellent and stable electrical properties. In addition, the electrophotographic photoreceptor can be prepared with relatively low manufacturing costs.
