Abstract
Provided are an image forming apparatus and an inspection method of an image reading section capable of precisely detecting dirt that adheres to a dustproof glass. The image forming apparatus is provided with an image forming section, an image reading section, and a controlling section. The image reading section has a light source, a sensor, and a dustproof glass. At the time of the compensation processing operation of the image reading section, the controlling section detects dirt on the dustproof glass on the basis of a detection value acquired by the sensor when light is emitted from the light source onto a reflective member for compensation that specularly reflects the light.
