Abstract

A wet type electrophotographic copying machine of the type capable of performing one copy making process during substantially two revolutions of a photoconductor, which is provided with means for forming a liquid developer deposition portion by charging, exposure and development, on the downstream side of an image formation area on the photoconductor, the liquid developer deposition portion capable of substantially narrowing the gap between the photoconductor and a squeegee roller, whereby the squeezing of excess developer from the surface of the photoconductor can be performed at the squeezing initiation point on the photoconductor, thus attaining a sharp squeezing effect, and the adhesion of the excess liquid developer to an image transfer material can be prevented.
