Abstract
A developing head is provided under a latent image carrier in the form of a rotating drum or a horizontally moving plate. The developing head includes a plurality of fountain slits and discharge slits arranged alternately in parallel to each other and extending laterally. A liquid developer jets out of supply openings provided in a hollow pipe member inserted in each cylindrical developer guide provided under the fountain slits and connected with the slits. The liquid developer jets move upward to the latent image carrier through the fountain slits and are discharged through the discharge slits located on both sides of the fountain slits.
