PROBLEM TO BE SOLVED: To realize an image quality desired by a user while keeping a consumed toner amount.SOLUTION: When a toner saving setting is performed, at a step S503, a system control part acquires a target toner saving amount set at a UI part, set information indicative of whether an avoidance object is provided in a toner saving state, and information on an avoidance object. As to the target toner saving amount, a toner reduction rate is acquired by a system control part. A system control part transmits the acquired information to a toner saving information processing part. At a step S504, the system control part determines whether an avoidance object set at the UI part exists in bit map image data. At a step S506, in the toner saving information processing part, the system control part adds a "necessary reduction amount 1" to a toner reduction amount at which an object other than the avoidance object is required to realize the target toner saving amount so as to calculate a "necessary reduction amount 2". |
