TANK FILLED WITH DEVELOPING LIQUID IN ELECTROPHOTOGRAPHIC APPARATUS

摘要

Developing apparatus for electrophotographic use includes a tank containing developing liquid, a cylinder having an apertured sidewall supported for rotation in the tank and a propeller creating reduced pressure within the cylinder. Sheets bearing electrostatic images are attracted to the cylinder and maintained in contact with the apertured sidewall by suction. Upon development the sheets are peeled from the cylinder by fingers juxtaposed with reduced diameter sidewall areas.
