Abstract
An embodiment of an image forming apparatus may include a photosensitive member, a development unit, a transfer member, a sensor, and a correcting unit. The development unit may form a toner image on the photosensitive member. The toner image member may be transferred onto the transfer member. The sensor may detect light from a surface of the transfer member. The correcting unit may correct a toner density in a first area of the transfer member after transfer of a toner image of a test pattern to the first area. The correcting unit may correct the toner density on the basis of a difference between an output value of the sensor from a second area before the transfer of the toner image of the test pattern and an output value of the sensor from the second area after the transfer of the toner image of the test pattern.
