Title: Contact electrification method and contact electrification device
Inventor: OFUKU EIJI
IPC: G03G13/02
Filed: 1992-10-01
Abstract: PURPOSE:To prevent the generation of ozone and to obtain a sufficient electrification potential with impression of a low voltage by electrifying a body to be electrified under the conditions under which the electrostatic capacity of a contact electrifying member, the electrostatic capacity of a body to be electrified and impression voltage satisfy a specific relation. CONSTITUTION:The roller-shaped contact electrifying member 1 is pressed to a drum- shaped photosensitive body (body to be electrified) 2 and a voltage is impressed between the contact electrifying member 1 and the photosensitive body 2 by a power source 3, by which the photosensitive body 2 is electrified. The photosensitive body is electrified under the conditions under which the electrostatic capacity C1 (Fmum<-2>) of the contact electrifying member 1, the electrostatic capacity C2 (Fmum<-2>) of the photosensitive body 2 and the impressed voltage Vr (V) satisfy the relation expressed by equation. In the equation, epsilon0 is the dielectric constant (=8.854X20<-18>Fmum<-1>) of vacuum. As a result, the generation of the ozone is completely suppressed and the sufficient electrification potential is obtd. by impression of the low voltage. The electrification efficiency is thus improved. Further, the generation of high-frequency sounds at the time of superimposing an AC voltage is prevented.
