ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC PHOTORECEPTOR CARTRIDGE, AND IMAGE FORMING APPARATUS |
摘要 |
<p>To provide an electrophotographic photoreceptor showing suitable electric characteristics, capable of forming a favorable image even after repeated use for long term and capable of forming a high quality image free from image defects such as a memory phenomenon, an electrophotographic process cartridge using such an electrophotographic photoreceptor, and an image forming apparatus using such an electrophotographic photoreceptor. An electrophotographic photoreceptor comprising a photosensitive layer containing oxytitanium phthalocyanine showing chief diffraction peaks at Bragg angles (2¸ ± 0.2°) of 9.6°, 24.1° and 27.2° to CuK± characteristic X-ray (wavelength: 1.541 Å) obtained by subjecting a phthalocyanine crystal precursor to chemical treatment and then bringing it into contact with an organic solvent, and a hydrazone compound represented by the following formula (1):</p> |
