PURPOSE:To prevent the entry of air in the developing liquid to be supplied to a developing part while the level of the developing liquid is low by providing a liquid suction member to a rotor revolving shaft for force supplying the developing liquid. CONSTITUTION:A casing 15 is provided in a developing vessel 12 into which the developing liquid 13 fed through the hole 11a of a developing electrode 11 and a pipe 18 is supplied. A rotor 14 to be revolved by a rotor revolving shaft 16 is provided in said casing. The shaft 16 is revolved by a motor 17. A liquid suction member 19 is mounted to the shaft 16 in the position in contact or proximity to or with the top surface of the casing 15. For example, sponge is used for the member 19, but any material is usable as far as it can be impregnated thoroughly with the developing liquid therein. Said member is made into a circular cylindrical shape. Even if the liquid 13 decreases down to a replenishing level H, the intrusion of air through the hole 15c penetrated in the shaft 16 into the casing 15 is prohibited. |
