A copying machine wherein a magnification ratio can be changed substantially continuously within a predetermined range, comprising means for setting a longitudinal magnification ratio of a copied image against an original and a lateral magnification ratio of a copied image against the original independently, image shifting means for shifting an image projected on a photosensitive drum in a direction away from a paper separation belt, first calculating means for calculating a lateral magnification factor, second calculating means for calculating a longitudinal magnification factor, and means for modifying the longitudinal and lateral copy magnification ratios respectively using the selected magnification ratio, the longitudinal and lateral magnification factors, whereby an image can be formed on the copy paper, preventing image drop out.
