PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which is highly sensitive, in particular, highly sensitive in a semiconductor laser wavelength area and supplies images having few image defects, such as ghosts, and to provide a process cartridge and an electrophotographic system which have the electrophotographic photoreceptor. SOLUTION: In the electrophotographic photoreceptor having a photoreceptive layer on a support, the photoreceptive layer contains an azotized calix [n] arene compound having a specific structure.
