Title: Wet image forming device
Inventor: MIYAZAWA YOSHINORI
IPC: G03G15/16
Filed: 1989-04-04
Abstract: PURPOSE:To always obtain a satisfactory transfer image without being affected with the surface roughness of recording paper by confronting a toner image temporarily transferred onto a transfer roll with the recording paper and pressure-transferring the image onto the recording paper. CONSTITUTION:A potential difference is produced between the transfer roll 4 and the aluminum raw tube of a photosensitive drum 5 to transfer the toner image on the photosensitive drum onto a transfer drum owing to an electrostatic field. Since the face of the transfer drum is smoothed, the toner image on the photosensitive drum is faithfully transferred onto the transfer drum. Then, the transfer roll 4 abuts on the recording paper, which is pressed by a pressure roll 13, and accordingly the toner image is transferred onto the recording paper. Consequently, even the recording paper is rugged, transfer is performed with the surface of the paper smoothed by pressure. Therefore, deterioration in a transfer image due to the type of paper can be prevented.
