摘要：
In a method for controlling magnification variation in which an original picture image is projected on a light receiving surface with a desired magnification, the projected picture image is moved in the sub-scanning direction which intersects the main scanning direction where the sensor is aligned, and the feeding speed (V) in the sub-scanning direction and the electric charge storage time are controlled.
