ABSTRACT:
A liquid developer wringing and removing apparatus in a liquid development type electrophotographic copying machine is provided with a conductive member. The conductive member of the liquid developer wringing and removing apparatus is maintained at a ground potential and disposed behind a developing station in an electrophotographic process facing to the surface of a photosensitive member keeping a small clearance therebetween. By doing so, the toner remaining on non-image portions of the development can completely be removed and the excessive toner can also be squeezed out properly. A member for cleaning the conductive member or a corona discharger behind the conductive member can be provided additionally for further improvement of the present invention.
