PURPOSE:To form an image of high precision by controlling the cycle of a main scanning synchronizing signal, which is outputted against an exposing device at the time of second image formation onward against a same paper responding to the elongation and contraction ratio of the paper. CONSTITUTION:A programmable controller 45 is controlled by a controlling signal from CPU 40, at the time of the second image formation, the cycle of the main scanning synchronizing signal is shortened to shorten the image length in a sub-scanning direction, responding to the contraction of the paper from fixing at the time of the first image formation. Furthermore, the setting value at the CPU 40 of the cycle of the main scanning synchronizing signal at the second image formation onward against the same paper is constituted to be arbitrarily settable/adjustable using an adjusting switch, etc., arranged on the side surface, etc., of a printer main body. Thus the image length can be compensated in the sub-scanning direction with high precision, responding to the elongation and contraction of the paper. |
