Abstract
An image forming apparatus includes: an optical sensor which includes a light-emitting part and a light-receiving part opposed to the light-emitting part and is configured to detect an amount of waste toner accumulated in a waste toner container, the waste toner being produced with formation of an image and then accommodated in the waste toner container; a detecting section configured to detect a change in an output of the light-receiving part; a shielding member interposed between the light-emitting part and the light-receiving part and configured to create, between the light-emitting part and the light-receiving part, a light-transmitting environment equivalent to that when the waste toner container is filled with the waste toner; and an adjusting section configured to adjust a light intensity of the light-emitting part when the shielding member is interposed between the light-emitting part and the light-receiving part.
