Abstract

PURPOSE:To assure satisfactory cleaning performance and high speed performance by providing a switch means for changing over a 2-turn process in which the destaticizing and cleaning of a photosensitive body are executed once in each one copying and a 3-turn process in which said destaticizing and cleaning are executed twice in each one copying. CONSTITUTION:A developing part 4, a transfer charger 5, a destaticizing charger 6, a destaticizing lamp 7, etc. are disposed around a photosensitive belt 1 and the operation timing of the belt is controlled when the slit provided to the side part is detected by a detector 15. A cleaning selection switch SW, a copying switch PSW, the detector 15, a paper feed detecting switch MS1, a paper discharge detecting switch MS2 and an original platen stop position detecting switch MS3 are connected to a microcomputer 14 which outputs control signals to devices 16-22 according to the set 2-turn process and 3-turn process to operate the devices so as to execute once or twice the destaticizing and cleaning of the belt 1 in each one copying. The good cleaning performance and high speed performance are thus assured.

<Prior art and its drawbacks> After the photoreceptors of photoreceptors 1 to 1 of a multi-fetch machine are exposed and developed and the image is transferred to a copying machine, some toner remains. In order to remove this residual 1.
After removing the charge on the photoconductor using a static elimination lamp, etc., the photoconductor is cleaned with electrostatic furan.This cleaning electrostatic brush is used to apply toner onto the photoconductor in the developing section. The method of using an electrostatic developing brush to develop the latent image has been widely used in the past because it helps make the A device smaller and lighter.
It is generally called a two-turn process because the photoreceptor ram rotates one or two times in one ink row. However, when high-resistance carriers such as resin-coated carriers began to be used in place of the conventional iron powder carriers, the cleaning properties of these systems became insufficient. In addition, today there are many cases in which high image quality is required for copying, so a three-turn process has been proposed in which the cleaning process is performed twice to improve cleaning. However, the cleaning performance of this method is not sufficient, as the photoconductor tram is rotated 3 times per copy, so the copying speed is slow, and when copying pale originals, the cleaning performance is sufficient, so it is necessary to rotate the photoreceptor tram 3 times. The drawback was that the eyes were wasted.
