PURPOSE:To perform development and cleaning within a small space by fitting a developing electrode and an ultrasonic wave oscillation device to a developer dish wherein a photosensitive body is dipped as to a liquid transfer type electrophotographic device. CONSTITUTION:The photosensitive film 2 charged by a corotron generating device 12 is exposed at an exposure position 10 and then dipped in the developer in the developer dish 20 to stock part of toner suspended in a solvent on the surface of the photosensitive film. Then, the surfaces of an exposed part and a toner sticking part are changed positively by a precharging device 40. A transfer material 44 is pressed at a transfer position 42 and the pressing of the transfer roller 48 operates on the photosensitive film 2 and transfer material 44 through cloth 46 to move the toner stuck on the photosensitive film 2 to the transfer material 44 and fix it. The film 2 moves continuously to enter a developing and cleaning device 14, where the ultrasonic oscillation device 26 operates to clean the surface of the photosensitive film 2 with the developer on an ultrasonic basis, thereby completing one operation of transfer. |
