Abstract

In a liquid-type developing apparatus of this invention, a developing head has a hollow portion having a slit-shaped opening having as a longitudinal direction a direction perpendicular to the convey direction of a recording sheet, and a partitioning wall for dividing the hollow portion into developing liquid flow-in and flow-out chambers and having a top portion located at the slit-shaped opening. A plurality of projecting portions and a plurality of recessed portions for constituting a developing portion are formed on the top portion of the partitioning wall. The plurality of projecting portions and recessed portions are alternately disposed at a predetermined pitch to form stripes in the longitudinal direction of the slit-shaped opening. The direction of the stripes is set to be oblique to the convey direction of the recording sheet. The height of each projecting portion is set to be equal to that of the slit-shaped opening, and the height of each recessed portion is set to be lower than that of the slit-shaped opening.
