Abstract

PURPOSE: To perform liquid development of less ground stains by adding film-forming material to the surface of a developer feed member.
CONSTITUTION: Film-forming material of 25dyne/cm or less, preferably 20dyne/cm or less in critical surface tension such as tetrafluoroethylene or copolymer of tetrafluoroethylene and hexafluoropropylene is coated and baked on the surface of a developer feed roller. Then, at the time when the electrostatic latent images having been formed on the surface of a xerograph drum 1 are developed by the liquid developer 7 contained in a containing tray 6 and having been coated by way of a developer coating roller 8 and developer feed roller 9 in the developing position 5 and are then transferred to a transfer web 14 in the transfer positon 11, the liquid developer 7 deposited on the convex parts of the surface of the developer feed roller 9 is surely removed by a blade 10 even when the liquid developer 7 is an organic solvent of small surface tension.
