摘要:
The present invention provides an electrophotographic photoreceptor comprising a photosensitive layer that contains at least a charge generating agent, a hole transport agent and a predetermined additive. The hole transport agent satisfies the following formulas (A) and (B). The electrophotographic photoreceptor prevents image defect from occurring and can meet the demand for higher speed image forming apparatuses, by reducing the adhesion of paper dust and preventing the occurrence of cracks. μ M 5.0 × 10 - 6 μ : Hole mobility ( cm 2 · V - 1 · second - 1 ) of hole transport agent in the electric field intensity of 3 × 10 5 ( V / cm ) M : Molecular weight of hole transport agent ( B )
