IMAGE FORMING APPARATUS AND METHOD OF CORRECTING IMAGE MISALIGNMENT
An image forming apparatus includes a transport member, image forming units (used as pattern forming unit), a pattern detector, and an image misalignment detector. The image forming units form correction-use patterns for each color on the transport member. The pattern detector directs a light beam o...

| description | An image forming apparatus includes a transport member, image forming units (used as pattern forming unit), a pattern detector, and an image misalignment detector. The image forming units form correction-use patterns for each color on the transport member. The pattern detector directs a light beam onto the transport member having the correction-use patterns and detect reflected light reflecting from the transport member. The image misalignment detector detects image misalignment of the correction-use patterns. The pattern forming unit forms a reference color pattern and a first color pattern. The pattern detector uses an irradiation light having a first wavelength matched to a spectral sensitivity peak of the first color pattern to detect an intensity of reflected light reflected from the transport member. The image misalignment detector computes an image misalignment value between the reference and first color patterns based on the intensity of reflected light reflected from the transport member. |
