PURPOSE:To reduce an image forming function part and to facilitate the manufacture, adjustment, maintenance, etc., of a recorder by forming two-color toner visible images continuously on photosensitive drums of a tandem constitution and copying them on a recording form superposedly and continuously. CONSTITUTION:The photosensitive drums 71 (72) are equipped with two image formation parts consisting of electrostatic chargers 73 and 76 (83 and 86), latent image formation part 74 and 77 (84 and 87), and developing parts 75 and 78 (86 and 88) which use the toner having different colors, and a transfer parts 79 (89) and a cleaning part 81 (91). Those drums 71 and 72 are arranged in parallel in the running direction of recording paper 94 and visible images are formed on the drum 71 during one rotation with the 1st and the 2nd color toner particles corresponding to the 1st and the 2nd color parts of an information image to be recorded by the two image formation part and transferred to the paper 94 at a time by a transfer part 79. Further, visible images are formed on the drum 72 during one rotation with the 3rd and the 4th color toner particles corresponding to the 3rd and the 4th color parts of the information image to be transferred to the same paper 94 at a time by a transfer part 89, thus performing a multi-color recording. |
