Abstract

PURPOSE: To obtain the good toner images of high density by providing a liquid well part in the lower part of the surface to be developed, providing a partition plate with liquid-through holes therein and supplying the developing solution evenly in unified flow form.
CONSTITUTION: Below the opening 2 extending in the width direction of the surface to be developed on a developing electrode 1 is provided a liquid well part 3 communicating with this and further a partition plate 5 provided with liquid-through holes 6 for parting said part vertically is secured within said liquid well part 3. The developing solution delivered by a liquid feed pump passes through a liquid feed pipe and is introduced into the inside. Since the partition plate 5 has such a shape that the distance from the opening part 2 becomes proportional to the pressure of each part of the influent developing solution, the solution having been spouted upward through the liquid-through-holes 6 receives the interference of the developing solution collecting on the partition plate 5 in proportion to the injection pressure, whereby it is evened until it reaches the opening. Thereby, the toner images formed are well maintained. Further a large amount of toner is evenly supplied and the images of high density are secured.
