摘要： An image forming apparatus includes a toner pattern bearer to bear a first toner pattern having a first image area and a second toner pattern having a second image area different from the first image area. 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： An optical scanning apparatus is constructed to detect one or more defective or damaged light emitting devices of a light source unit and forms images having substantially the same quality as that of the images formed when all of a plurality of light emitting devices of a light source of the apparatus are functioning normally even when any one of the plurality of light emitting devices are damaged or broken, without decreasing the image forming performance of the apparatus. The optical scanning apparatus detects one or more damaged or broken light emitting devices and then compensates for the light omitted due to the damaged or broken light emitting devices using the normally functioning light emitting devices without decreasing the image forming speed or quality of the optical scanning apparatus. In order to compensate for a defective light emitting device, the optical scanning apparatus uses various solutions such as increasing the rotating speed of the deflector while increasing the modulation speed of the light emitting devices by the same amount, increasing beam spot diameter in the subscanning direction, changing the output power of the light emitting devices on a surface to be scanned in order to increase beam spot diameter in the main scanning direction and the subscanning direction, and changing the focal length of the line image forming optical apparatus and increasing either the rotation speed of the deflector or the rotation speed of the surface to be scanned or photoconductive drum.
