CONTACT ELECTRIFYING DEVICE, METHOD FOR CONTACT ELECTRIFYING AND ELECTROPHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a contact electrifying device with which a good image can be obtained by using an electrifying body which can be uniformly electrified without nonuniformity and has excellent cleaning properties, and to provide a method for contact electrification by using the device and an electrophotographic device equipped with the device. SOLUTION: In the contact electrifying device to electrify a body to be electrified by externally applying voltage to an electrifying member disposed in contact with the objective body, the contact electrifying member has a resistance layer and a surface layer having >=1.4μm and <=2.4μm surface roughness Rp (average line height) and <=1.45μm Rv (average line depth) and containing a conducting agent in N-alkoxymethyl nylon. The contact electrifying device, the method for contact electrification and the electrophotographic device are characterized in that the voltage externally applied is a pulsating voltage generated by superposing a DC voltage and an AC voltage.
