摘要： PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor and a color image forming apparatus which can sufficiently prevent color irregularity even when color images are repeatedly formed. SOLUTION: The electrophotographic photoreceptor 1 has a single-layer type photosensitive layer 3 formed on a conductive substrate 2. The photosensitive layer 3 contains gallium phthalocyanine. As the hole transport property of the gallium phthalocyanine is high in the photosensitive layer 3, the photosensitivity is increased and changes in the photosensitivity by temperature changes or humidity changes can be sufficiently prevented. As the photosensitive layer 3 has a single layer structure, even when holes are produced by excitation by light and the holes move to the surface, repulsion against mobile charges in the same polarity is sufficiently prevented and the resolution in the photoreceptor can be sufficiently increased.
