摘要:
An image forming apparatus includes a latent image bearer, a toner image forming unit, and a transfer device. The toner image forming unit includes a charger, a latent image forming device, and a developing device, and is configured to form a test latent image pattern on a surface of the latent image bearer, and to develop the test latent image pattern into a test toner pattern. The test latent image pattern includes a plurality of test latent image parts partly offset from one another in a main scanning direction. The image forming apparatus also includes a developing current detector and a processor to detect uneven image density in the main scanning direction using the test latent image pattern, based on the developing current detected by the developing current detector, to adjust the uneven image density in the main scanning direction.
