Abstract

An image forming apparatus includes an image forming unit to form an image on a recording medium; an inverting transport unit to invert first and second surfaces of the recording medium, and front and rear ends of the recording medium to transport the inverted recording medium; a recording medium width measuring unit to measure an end position of the recording medium in a width direction orthogonal to a transporting direction of the recording medium at a measuring position having an approximately identical distance from one end of the recording medium in the transporting direction before and after the image is formed on the recording medium; and a correcting unit to correct an image to be formed on a subsequent recording medium based on a change in a shape of the recording medium computed based on a measured result from the recording medium width measuring unit.
