ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor having high sensitivity and a long service life. SOLUTION: In the electrophotographic photoreceptor with at least a photosensitive layer on the electrically conductive substrate, a polyarylate resin having no nitrogen atom in its repeating units is contained in the photosensitive layer and the hole mobility of the photosensitive layer at 3×105 V/cm electric field intensity and 21 deg.C is >=3×10-6 cm2/Vs.
