Abstract: An image forming apparatus includes a density detector, a determination unit, and a change unit. The density detector detects a density of a patch image formed on an image carrier over plural places. The determination unit determines whether plural detection results of the density detector are within a threshold. When the number of determination results, by the determination unit, that the density of the patch image is not within the threshold exceeds a predetermined number, the change unit changes (i) a detection timing at which the patch image is detected by the density detector or (ii) a formation position of the patch image on the image carrier.

Abstract: To reduce the damage to the inner portion of a seat back caused by the mounting part of a headrest on the seat back. A vehicle seat (S) includes a headrest guide (6) having an insertion hole (6A) into which a headrest stay (12) of a headrest (S3) is inserted, a holder (8) mounted on a seat back frame (2) and configured to hold the headrest guide (6), and a cover member (10) configured to cover at least a part of the outer surfaces of the headrest guide (6) and the holder (8) and detachable from the seat back frame (2).

Abstract: An image forming apparatus includes a developing device that performs a developing process by using two-component developer; an image carrier that carries a toner image including a toner band developed by the developing device; a density detection unit that detects a density of the toner band; and a determining unit that determines whether or not to perform a density adjustment on the basis of the density of the toner band detected by the density detection unit.

Abstract: An image forming apparatus includes a density adjusting unit that executes first formation of forming a first color sample in a transfer area on an image carrier, first adjustment of adjusting output characteristics of an image forming unit to reduce a difference between a measured density of the first color sample and a first target density, second formation of forming a second color sample in a non-transfer area on the image carrier, second adjustment of adjusting the output characteristics to reduce a difference between a measured density of the second color sample and a second target density, and third adjustment of adjusting the output characteristics to reduce a difference in output density between the transfer and non-transfer areas, if the difference between the measured density of the second color sample and the second target density exceeds a predetermined extent after repeating the second formation and the second adjustment.

Abstract: Provided is an image detection device including a light-emitting unit that emits light toward an image holding member, a first light-receiving unit that is disposed at a position where specular reflected light of the light emitted toward the image holding member is received, a second light-receiving unit that is disposed at a position where diffuse reflected light of the light emitted toward the image holding member is received, a light-emission control unit that controls an intensity of the light emitted by the light-emitting unit, and a reference member that is disposed at a position through which light having an intensity that is less than an intensity detectable by the second light-receiving unit passes in a case of the first intensity and through which light having an intensity that is equal to or higher than the intensity detectable by the second light-receiving unit passes in a case of the second intensity.
