Abstract:
In an image forming apparatus, a storage portion stores a target adhesion amount of toner to adhere to an image bearing member at each of gradation levels as a target gradation level and a setting value of a control parameter used for control on the image forming portion at the target gradation level. A first control processor makes an adhesion amount sensor measure an actual adhesion amount corresponding to the setting value and thereafter compares a resultant measured value and the target adhesion amount and corrects the setting value if needed in association with at least one of the target gradation levels as a subject. A second control processor makes the image forming portion output a calibration image used for correcting the target adhesion amount using a period when the first control processor performs processing if there arises a need to correct the target adhesion amount associated with the subject.

Claim (Index 8):
A method of controlling an image forming apparatus, the image forming apparatus comprises: an image forming portion that forms a toner image on an image bearing member; an adhesion amount sensor that measures an amount of toner adhering to the image bearing member; a controller that controls the image forming portion and the adhesion amount sensor; and a storage portion, in association with gradation levels of each color forming certain color space, the storage portion stores a target adhesion amount of toner to adhere to the image bearing member at each of the gradation levels as a target gradation level,\n the method comprising a step of: (i) determining, in association with at least one of the target gradation levels as a subject, whether or not correction of the target adhesion amount associated with the subject target gradation level is necessary, and if the correction is determined to be necessary, making the image forming portion output a printed matter of a calibration image, which is used in the correction of the target adhesion amount, at an output position which is shifted from another output position for other printed matters.
