Abstract
PURPOSE:To prevent the occurrence of deviation in formed images by altering image forming magnifications after a second image formation based on at least one result of the detected result and the inputted result in a control means. CONSTITUTION:When a signal from a temperature and humidity sensor 80, a signal from a transfer sheet size sensor 81 and the signal of the kind of paper from an operation part 82 are inputted to a MPU 85, the optimum copying magnification alpha is selected by referring to the above-mentioned data and the data which is obtained by an experiment and stored in the memory 86 of the MPU 85. When the image is formed for the second time, the signals are added to a motor 85 which adjusts the position of the zoom lens of an optical system and the scanning motor 50 of the optical system through a motor driver 83 and the second image formation is executed with the optimum copying magnification alpha. Then, the second image formation can be executed considering the reduction of the transfer sheet after the first image formation. Thus, the deviation between the first image and the second image can be prevented.
