PURPOSE:To prevent image flowing caused by dew condensation on the surface of a body to be electrified, due to the thermal conductivity of a vibration proof material, the moisture adsorption of paper powder stuck to the surface of the body to be electrified reduction in the resistance of the surface to be electrified, even if the vibration proof material is included in the body to be electrified, in an image forming device provided with a contact electrifier for electrostatically charging the surface of the body to be electrified, to a prescribed potential. CONSTITUTION:A transfer material feeding means 10 is arranged on the part of a transfer material feeder 7 corresponding to an extension region A in a transfer material carrying direction, between, at least, one end part of the part of the vibration proof material 2c included in the body to be electrified 2, and its end part on the same side as the one end part, and a constitution that when a distance between a product C in the transfer material carrying direction, on the end part of a vibration proof material part, and a product D in the transfer material carrying direction, on the inside end part of the transfer material feeding means, is d[mm], and the thermal conductivity of the vibration proof material is k[W.m<-1>.K<-1>], the relation of d>12logk-20 (the log is a common logarithm) is satisfied, is adopted. |
