| description | PROBLEM TO BE SOLVED: To provide an image forming apparatus presenting the accurate remaining amount of consumables to a user to notify the user of a suitable replacement timing of the consumption article. SOLUTION: The image forming apparatus includes a remaining consumable calculating unit 105 which calculates the remaining amount of the consumables from the consumable charging amount 101 of a toner cartridge, a cartridge driving time 103, and a correction coefficient αnew, and a sensor 107 which detects that the consumption are used up. An empty consumable remaining amount calculating unit 109 finds a calculated value B of the consumable remaining amount calculating unit 105 when the consumables are actually used up from empty information of the sensor 107 to calculate the correction coefficient αnew from consumable charging amount information A and the calculated value B.
