り清掃され、再び帯電プロセスに入る。Next, the operation will be explained. The photoconductive drum (11) is corona-charged by the charged electrode (21) in the dark. When the light corresponding to the number of printing marks hits the photoconductive drum (11) by the light-emitting diode array (3), the photoconductive drum (1) An electrostatic latent image is created. When the electrostatic latent image is developed by a developing machine (411), toner (powder ink) is formed into a Z page. The toner image is transferred to a transfer pole (6 Paper 15)
Transfer to. The toner on the recording paper is fixed by the fixing device (No. 81) and printing is completed. On the other hand, the photoconductive drum (No.
The remaining toner remaining after transfer on the surface of the toner 1 is cleaned by the cleaning step (7) I, and the charging process is started again.

101) (102) (103) are flexible graded optical fibers, and (1) is a photoconductive drum. The printing process is exactly the same as the conventional one, but whereas conventionally, the area exposed to light by the light emitting diode array is printed one line at a time, in the present invention, the area exposed to light is printed once by multiple light emitting diode arrays (31) (32) (33). Can print multiple lines.

T-ray (31) (33) is placed at a position of 1011 from the light emitting surface, and the other is placed at a position of approximately 1011 from the photoconductive drum fil.
There is no 1+1, but if the image formation is arranged so that it is, for example, Q, l, it is possible to simultaneously draw multiple lines at minute distances even if a large light emitting diode array is used.
