Patent JP-H06202500-A (JP)
Title: Image forming device
Inventor: ONO KAZURO
IPC: G03G15/16
Filed: 1992-12-30
Abstract: PURPOSE:To prevent a failure in a transfer at the time of successively transferring/laminating a toner image on an image carrier on an intermediate transfer body. CONSTITUTION:The toner images of magenta M, cyan C, yellow Y and black B are successively formed on a photosensitive drum 1 and intermediately transferred on an intermediate transfer roller 6, to laminate the toner images of four colors on the transfer roller 6. At the time of transferring these images a voltage having the characteristic opposite to that of toner is applied to the transfer roller 6 by a constant voltage power source 30. A transfer electric field by the voltage is weakened by the toner image which has already been transferred on the transfer roller 6. At this time, whenever the transfer is repeated, the voltage is made high and the transfer electric field is always made excellent.
