Zusammenfassung:To allow for determining whether a consumable memory is usable or not without using information indicative of the number of times information has been written to the consumable memory when a consumable is filled with a printing material without replacing the consumable memory.SOLUTION: A controller (61) of an image forming device (1) provided herein performs determination processing for determining whether a toner memory (42) can be continued to be used or not after print volume information is changed, on the basis of capacity information stored in the toner memory (42) and print volume upper limit information stored in the toner memory (42) or a main memory (62).SELECTED DRAWING: Figure 2 【課題】消耗品メモリが交換されない状態で消耗品に印刷材が充填される場合に、消耗品メモリへの情報の書き込み回数を表す情報を用いることなく、消耗品メモリを使用できるかを判定する。【解決手段】画像形成装置(1)のコントローラ(61)は、トナーメモリ(42)に記憶される容量情報と、トナーメモリ(42)または本体メモリ(62)に記憶される上限印刷量情報とに基づき、印刷量情報が変更されてもトナーメモリ(42)を継続して使用できるかを判定する判定処理を実行する。【選択図】図2
