Image forming apparatus

Abstract

There is provided an image forming apparatus capable of suppressing fluctuation of sensor output. The image forming apparatus includes a photosensor and a hardware processor. The photosensor has a layered structure in which a surface layer is laminated on a base material layer, irradiates a surface of an image bearing member on which a toner image is formed with detection light on the basis of a predetermined detection condition, and receives reflected light of the detection light reflected from the surface of the image bearing member. The hardware processor controls at least a dominant wavelength of the photosensor among the predetermined detection conditions such that light interference and dark interference are included in the reflected light, and controls a toner adhesion amount onto the image bearing member on the basis of an output of the photosensor.
