Image forming apparatus and control method thereof

摘要

An image forming apparatus includes a transport part (110) which includes a transport belt (110a) to transport a printing medium, an image forming part (120) which transfers a toner to form a color image, and a controller (140) which controls the image forming part (120) to form a test image for color registration of the image forming part (120) on the transport belt (110a) while an image is formed for a plurality of printing media. Thus, both a test image and a plurality of printed media are formed during a single printing process.
