PURPOSE:To stably form a recorded image with high resolution on a plain paper by opposing recording electrodes juxtaposed on a developer carrying member to a cylindrical electrode which is combined with an intermediate recording medium with a very small gap and setting a cleaning electrode on which the voltage of a reverse polarity to the electrostatically charge polarity of the developer is impressed on the surface part of the developer carrying member on an upstream side. CONSTITUTION:The leading edge part 20al of a recording electrode line 20a positioned in a recording part W is made to rise a little and exposed to the surface of an insulat ing coat 20c, then a recording action is performed. The cleaning electrode 20d made of a non-magnetic conductive material is disposed at a position set at specified length apart from the leading edge exposed part 20al of the recording electrode line to the upstream side, and a cleaning power source 20e capable of outputting the DC voltage of a reverse polarity to the electrostatically charged polarity of developer is interposed between the electrode 20d and a cylindrical electrode 5, and toner d0'' which is not transferred and left on the circumferential surface of the electrode 5 is transferred to the electrode 20d side so as to clean the circumferential surface of the electrode 5. Thus, the plain paper is used and the excellent recorded image with the high resolution is stably formed without causing an after-image. |
