To provide an electrifying device which does not generate ozone or the like, has a long service life, seldom damages a body to be charged, and enables an efficient electrifying.

In an electrifying device, having a brush-shaped surface which makes contact with the body to be charged, the functions of wires are separated by the radius of each wire so that stress applied to the electrifying device is absorbed by thicker support wires 112 with suitable elasticity and thinner wires 113 have a function to contribute to the electrification.
