PROBLEM TO BE SOLVED: To provide an image recorder without transferring an image noise caused by a peeling discharge to a recording paper. SOLUTION: The control circuit of the image recorder is constituted of a CPU 51. When humidity detected by a humidity sensor 30 exceeds a prescribed value, it is judged that an environmental condition is apt to cause the peeling discharge, so that the operation period of a timing roller 26 is controlled to make a recording paper interval longer than the length in the circumferential direction of a photoreceptor and the scan starting period of a scanning optical system 10 is controlled in accordance with the operation period of the timing roller 26. Thus, image data of each color of yellow, magenta, cyan and black are timely outputted to electrophotographic processing units 22, 23 and 24, then an image is formed on the photoreceptor at a period corresponding to the prolonged recording paper interval and transferred to the recording paper. |
