ABSTRACT:
The image developing part 10 is constructed from the developing agent storing part 20 storing the fluid developing agent 18 and the developing agent supplying part 22 confronting the surface of the photosensitive drum 12 via the minute opening 25. The developing agent supplying part 22 includes a pair of, upper and lower, flat plates 24a and 24b which are placed in parallel and which define the uniform minute opening 25 over an entire width of the photosensitive drum 12. The flat plates 24a and 24b are formed with the electrodes 26a and 26b, respectively. It is possible to finely adjust the gap between the flat plates 24a and 24b through operating the minute displacement actuator 28 placed at the gap between the flat plates 24a and 24b. It is therefore possible to control the pressure to be exerted upon the fluid developing agent 18.
