ABSTRACT:
The invention provides a method for cleaning squeeze rollers of a liquid electrophotographic developing apparatus by a cleaning pad which makes it possible to develop an electrophotographic photoreceptor with causing no stains. The method includes the steps of supplying a solvent for liquid developer to a pair of squeeze rollers thereby to clean the rollers with the solvent; isolating the squeeze rollers from each other; and allowing one of the rollers which contacts with photosensitive surface of photoreceptor and the cleaning pad to contact with each other thereby to clean the roller kept isolated from the other squeeze roller by the cleaning pad. The invention further provides a liquid electrophotographic developing apparatus for carrying out the method.
