Zusammenfassung:To provide an image forming apparatus that can perform printing even though drum memory communication cannot be performed.SOLUTION: An image forming apparatus comprises: drum cartridges to which toner cartridges are attached; a housing to which the drum cartridges having the toner cartridges attached thereto are attached; a voltage application unit that applies a voltage to chargers; and a control unit that performs print control. The drum cartridges respectively include the chargers that charge photoreceptor drums, and drum memories that store drum information. The control unit determines if it can communicate with the drum memories, and when determining that it cannot communicate with the drum memories, applies a voltage to the chargers and determines whether printing can be performed on the basis of a result of the application. The control unit performs printing on the basis of a result of the determination.SELECTED DRAWING: Figure 4 【課題】ドラムメモリ通信が行えなくても、印刷が可能な画像形成装置を提供する。【解決手段】画像形成装置は、トナーカートリッジが装着されるドラムカートリッジと、トナーカートリッジが装着された状態のドラムカートリッジが装着される筐体と、帯電器に電圧を印加する電圧印加部と、印刷制御を行う制御部とを備える。ドラムカートリッジは、感光体ドラムを帯電させる帯電器と、ドラム情報を記憶するドラムメモリを有する。制御部は、ドラムメモリと通信可能かを判定し、通信可能でないと判定した場合、帯電器へ電圧を印加し、その結果に基づいて、印刷可能かを判定する。そして、判定結果に基づいて、印刷を実行する。【選択図】図4
