摘要： An image forming apparatus includes a toner pattern bearer to bear a first toner pattern having a first image area rate and a second toner pattern having a second image area rate different from the first image area rate. A toner adhesion amount detector detects a toner adhesion amount of toner of each of the first toner pattern and the second toner pattern. A toner degradation rate calculator calculates a first deviation in the toner adhesion amount of the first toner pattern and a second deviation in the toner adhesion amount of the second toner pattern based on the toner adhesion amount detected by the toner adhesion amount detector. The toner degradation rate calculator compares the first deviation with the second deviation and calculates a toner degradation rate based on a comparison result.

摘要： The present invention includes an optical system disposed on an optical path of light that is emitted by a light emitting section, travels to a detection target object, is reflected by the detection target object, and reaches a light receiving section. The optical system, in a sub scanning direction, that is, the direction in which a detection target object is moving, collects light so that the light receiving section has, for light from the light emitting section, a regularly reflected light receiving area and a diffuse-reflected light receiving area that differ from each other in position within a predetermined range. The optical system, in a perpendicular direction that is perpendicular to the movement direction, refracts light so that a light receiving area, which covers the regularly reflected light receiving area and the diffuse-reflected light receiving area, is wider in the perpendicular direction than in the sub scanning direction.

摘要： A toner density is calculated from outputs of light-receiving elements based on a difference between a reflection property of a supporting member and a reflection property of a toner pattern. Light-emitting elements aligned in one direction that is inclined to a sub-direction emit a detection light in such a manner that a distance between adjacent spots falling on the supporting member in a second direction is equal to or smaller than a width of the toner pattern in the second direction. The light-receiving elements receive a reflected light reflected from the supporting member and/or the toner pattern. The light-receiving elements are aligned, opposed to the supporting member, in a one direction corresponding to the light-emitting elements.

摘要： An image forming apparatus includes an image carrier, an image forming unit configured to form a patch image on the image carrier, and a light emitting unit. In addition, a light receiving unit receives light reflected by the patch image when the patch image that moves with movement of the image carrier is irradiated with light by the light emitting unit, and includes one or more light receiving elements. A setting unit sets a first subset of light receiving elements for receiving reflected light from a first patch image and sets a second subset of light receiving elements for receiving reflected light from a second patch image, with the number of light receiving elements in the first subset differing from that in the second subset.
