Abstract
An image forming apparatus includes an image forming portion, a transfer unit, a power supply, and a reader. A test chart is formed by transferring test images to a recording material while applying test voltages from the power supply to the transfer unit. A transfer voltage to be applied to the transfer unit during transfer is set based on the read test images. A reference image is formed on the test chart. The reader reads the test chart by scanning the test chart from a first position to a second position that falls within the test images. The first position falls within a boundary of the recording material on which the test chart is formed and falls outside the test images. Based on the reference image, the result of the reader reading the test chart is obtained by scanning the test chart from the first position to the second position.
