Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a charging member that suppresses, over a long period, the occurrence of streak-like images resulting from an increase in resistance due to conduction deterioration of the charging member; and a process cartridge and an electrophotographic device that can suppress the occurrence of streak-like images, and stably form high-quality electrophotographic images.SOLUTION: There is provided a charging member that has a conductive support, and a conductive surface layer. The surface layer includes: at least one of compounds represented respectively by the formula (1), formula (3), and formula (4) defined in the specification; a binder resin; and a conductive agent. Also provided are a process cartridge and an electrophotographic device using the charging member.
