PURPOSE:To obtain a vivid print of a high toner density and a hard copy of a high print quality, by forming an erecting image and an inverted image of the same contents on the same recording medium and by transferring only a required image on a print medium. CONSTITUTION:A recording belt 16 is moved in the direction of an arrow D, and the surface of the belt 16 is charged electrically by corotrons 17 and 17'. Next, the belt 16 is pressed between electrodes 12 and 12' and rollers 14 and 14', and an erecting image and an inverted image of the same contents are formed as latent images from electrodes 12 and 12' respectively, and these latent image are developed by developers 13 and 13' to form an erecting image 3 and an inverted image 10. If a hard copy is required, an operator 5 closes a switch 25 and turns an arm 22 in the direction of an arrow B to rotate and drive a roll 29 and carrying rollers 31 and 31', and a print medium 11 is carried in the direction of an arrow C while bringing the print medium 11 into contact with the belt 16. Thus, the inverted image 10 is transferred as the erecting image 3 on the medium 11. |
