Abstract:
An image forming apparatus includes an intermediate transfer belt, a density sensor, a cleaning device and a density correction unit. The intermediate transfer belt carries a calibration toner image. The density sensor detects a density of the calibration toner image that passes at a predetermined position. The cleaning device contacts to a part of the intermediate transfer belt in a primary scanning direction, and removes from the intermediate transfer belt the calibration toner image that passed at the predetermined position. The density correction unit performs density correction of a printing toner image in the primary scanning direction. Further, the density correction unit changes a strength of the density correction for a contact range to which the cleaning device contacts on the intermediate transfer belt, the strength changed in accordance with the number of times of a calibration process.

Claim (Index 5):
An image forming apparatus, comprising:\n an intermediate transfer belt configured to carry a calibration toner image; a first optical sensor configured to (a) irradiate with light a predetermined first position at which the calibration toner image passes and (b) receive reflection light from the first position; a calibration processing unit configured to perform a calibration process based on an output signal of the first optical sensor, the output signal corresponding to the calibration toner image; a cleaning device configured to (a) contact to a part of the intermediate transfer belt in a primary scanning direction and (b) remove from the intermediate transfer belt the calibration toner image that passed at the first position; a second optical sensor configured to (a) irradiate with light a predetermined second position and (b) receive reflection light from the second position, the second position being a position other than a contact range to which the cleaning device contacts on the intermediate transfer belt; and a density correction unit configured to perform density correction of a printing toner image in the primary scanning direction; wherein the density correction unit changes a strength of the density correction in the contact range on the basis of (a) an output signal of the first optical sensor and (b) an output signal of the second optical sensor, the output signal of the first optical sensor corresponding to a surface material of the intermediate transfer belt at the first position, and the output signal of the second optical sensor corresponding to a surface material of the intermediate transfer belt at the second position.
