Title: Electrophotographic apparatus
Inventor: SAITOU TAKASHI
IPC: G03G21/00
Filed: 1978-07-05
Abstract: PURPOSE: To prevent solidified toner from damaging potoreceptor surface and blade by supplying cleaning solution before the apparatus starts working to wet the solidified toner near the photoreceptor and blade then performing cleaning.  
     CONSTITUTION: When the main switch of the apparatus is turned ON, the driving source 7 of a pump 6 actuates. The developer 5 in a tank 4 is then fed into pipe 9 via distributing means 8 and is supplied from a spray  pipe 10 onto the blade 11 of a cleaning means 3 and photoreceptor surface. The liquid having been supplied flows to the right and left along the blade and is then recovered. During this time, the solidified flows to the right and left along the glde and is then recovered. During this time, the solififed toner of the blade and photoreceptor surface is wetted. Next, the photoreceptor 1 is rotated by turning ON the copy switch to advance copying process and at the same time the distributing means 8 is changed over tothe developing through 2' of the developing means 2. Then, wetting of the solidified toner may be achieved and failure owing to neglection of supply of cleaning solution may be prevented
