Abstract
In a developing head of an electrophotographic system which develops an image by bringing a liquid developer into contact with a photosensitive face of electrophotographic material, through an opening provided in the developing head, a right angle is formed between the photosensitive face and the in-flow and out-flow route for the liquid developer and a gas for removing excess developer at the opening. A pressure-reducing chamber is formed between a frame around the opening and a frame surrounding the pressure-reducing chamber, both frames tightly contacting the electrophotosensitive material. Thus, the gap between the photosensitive face and a developing electrode is reduced and high speed for the gas for removing the developer is obtained. Liquid developer exuding from the frame around the opening is captured in the pressure-reducing chamber.
