PROBLEM TO BE SOLVED: To surely avoid collisions between a paper sheet from a paper sheet housing part and that having a picture-image-formed on a single surface, and between mating paper sheets having a picture-image-formed on a single surface, respectively. SOLUTION: In a picture image forming device where a paper sheet from paper sheet housing parts 1a, 1b, 1c, and 1d, and that having a single picture- image-formed surface, are alternately supplied to a transfer belt 5; plural standby parts 91 and 92, where a paper sheet, having a picture-image-formed on a single surface is stopped and stood by, are provided on a circulative carrying path 9 for circulatively carrying paper sheets having a picture-image-formed on a single surface respectively in order to form the picture image on a second surface. For avoiding collision with a recording material from the housing parts, collision between mating paper sheets having a picture-image-formed on a single surface respectively can be surely avoided by adjusting a stop time in another standby part 91 even a stop time in one standby part 92 is long. |
