摘要：
A device that estimates carrier deterioration indicating a degree of deterioration of carrier inside a developing device using a two-component developer includes a first carrier deterioration calculation unit, a second carrier deterioration calculation unit, and a carrier deterioration degree output unit. The first carrier deterioration calculation unit uses toner consumption and agitation time to calculate a first carrier deterioration degree indicating a degree of carrier deterioration caused by a spent phenomenon. The second carrier deterioration calculation unit uses the toner consumption and the agitation time to calculate a second carrier deterioration degree indicating a degree of carrier deterioration caused by a carrier abrasion phenomenon. The carrier deterioration degree output unit uses the toner consumption to select one of the first carrier deterioration degree and the second carrier deterioration degree, and outputs the selected carrier deterioration degree.
