Abstract
An image forming apparatus which corrects a transfer amount of a recording material without a scanner is provided. A paper is transferred to a position in which the transfer amount is adjusted by an LF roller, and a test pattern image in which a first pattern image and a second pattern image are printed in different transfer positions. Then, the paper is transferred to a position in which the transfer amount is adjusted by an exit roller, and the aforementioned test pattern image is printed. The test pattern images printed as above are used to visually observe and determine a degree of error in the amount transferred by the respective rollers. Accordingly, by receiving an input based on the printed test pattern images, it is possible to correct the transfer amount of the respective rollers.
