ABSTRACT:
The present invention discloses a wet type electro-photographic recording apparatus having a simple structure and a high quality without uneven density, and capable of miniaturizing the apparatus. Around a rotary drum, an exposing section, a pre-bath treatment portion and a developing portion are disposed. The exposing section is disposed on an upstream region in a rotating direction of the rotary drum with respect to a lower extreme position of the rotary drum, and in an upper portion of the rotary drum. The pre-bath treatment portion is disposed at a position between the upper portion where the exposing section is disposed and the lower extreme position of the rotary drum. The pre-bath treatment portion has at least a supply section provided at a high level position for dropping pre-bath liquid and a pre-bath coating section provided in a lower level position for coating the dropped pre-bath liquid on the electro-photograph recording sheet, whereby the electro-photographic recording is pre-bathed by using the high insulating liquid having phase solubility with electrically insulating liquid used as a wet type developer. The developing section having a developing electrode is disposed substantially close to the rotary drum and in an upstream in the rotating direction of the rotary drum with respect to the lower extreme position of the rotary drum.
