That is, photosensitive drum 31, which is an image carrier, rotates clockwise as shown by the arrow , and after pre-exposure for charge removal by static eliminator 36, charge is given to photosensitive drum 31 by charger 32, so that an electrostatic latent image corresponding to the image of original D is formed on photosensitive drum 31 by laser beam L from image writing unit 20. Thereafter, the electrostatic latent image on photosensitive drum 31 is reverse-developed by developer carried on developing sleeve 33A, which is a developer carrier to which a bias voltage of developing unit 33 is applied, to become a visible toner image.

Meanwhile, transfer paper P of a specified size is conveyed one sheet at a time from paper feed cassette 41A or 41B loaded in paper feed section 40 by conveyance roller 42A and fed toward image transfer section 70 via conveyance roller 43 and guide member 42. The fed transfer paper P is sent onto photosensitive drum 31 by registration roller 44, which operates in synchronization with the toner image on photosensitive drum 31. The toner image on photosensitive drum 31 is transferred onto this transfer paper P by the action of transfer device 34, and the toner image is separated from photosensitive drum 31 by the discharging action of separator 35. After that, the transfer paper P is sent to fixing section 37 via conveyor belt 45, where it is fused and fixed by fixing roller 100 and pressure roller 200, and then discharged to tray 54 outside the apparatus by paper discharge rollers 38 and 46. Reference numeral 53 denotes a paper feed table for manual feeding.
