IPC: G03G15/11
Filed: 1988-11-01
Abstract: PURPOSE:To improve transfer efficiency by developing electrostatic latent image by a reversal developing method with developer, removing excessive developer by a non-electrical squeezing system after development and before the transfer of visible pictures, and transferring the visible pictures onto specified transfer papers by electrostatically transferring. CONSTITUTION:The electrostatic latent image formed on a photosensitive body 10 is developed by the reversal developing method with developer 145, and after its development, excessive developer 145 on the photosensitive body 10 is squeezed by the non-electrical squeezing system 144. Besides, visible pictures are transferred onto the transfer paper S whose oil absorbing coefficient and smoothness are under 2.0X10<-2>cm/sec and over 200sec, respectively, by electrostatically transferring. Consequently, the transfer efficiency of the visible pictures becomes higher, practically 100%, and cleaning effects as expected. Thus, the damage is the photosensitive body 10 and fluctuation of this surface velocity coused by cleaning do not occurs, and excellent picture recording can be realized.

Filed: 1986-11-21
Abstract: PURPOSE:To improve detection accuracy and to improve operation stability by allowing a negative pressure sensor arranged in a processing liquid passage to detect the pressure of the flow passage when a control valve is opened to supply a replenishing liquid, and detecting whether or not there is the replenishing liquid according to the detection output. CONSTITUTION:The negative pressure sensor 32 is provided in the liquid developer flow passage including a concentrated toner flow passage connecting a developing head 22, a suction pump 23, and the control valve 31, i.e. at some positions facing pipes 26 and 28. When the suction pump 23 beings to operate, the pressure at the negative pressure sensor part begins to drop and a liquid developer 21 begins to circulate in the flow passage If the replenishing toner runs out when the control valve 31 is opened to supply the replenishing liquid, the negative pressure sensor 32 communicates with the atmosphere by the intervention of air which is small in fluid resistance, so the pressure at the negative sensor part 23 rises greatly. The supply liquid is supplied by the simple constitution which generates a replenishing toner running-out signal from the sensor output utilizing said pressure rise.
