Summary:PROBLEM TO BE SOLVED: To provide an image forming system configured to guarantee performance of a second cartridge when a false detection is caused by detection means, and an image forming apparatus.SOLUTION: When a first developing cartridge 11A and a third developing cartridge 11C, which are unlikely to cause a false detection of specifications, are mounted in an image forming system formed by selectively mounting multiple kinds of developing cartridges 11 on a device body 2, a developing bias lower than that to be obtained when a second developing cartridge 11B which is likely to cause a false detection of specifications is mounted, is applied to a developing roller 15. When the second developing cartridge 11B is falsely detected as the first or third developing cartridge 11A, 11C, toner consumption is reduced, to guarantee the maximum number of sheets with images formed thereon of the second developing cartridge 11B. 【課題】検知手段による誤検知が発生した場合に、第２カートリッジの性能を保証できる画像形成システムおよび画像形成装置を提供すること。【解決手段】複数種類の現像カートリッジ１１を選択的に装置本体２に装着する画像形成システムにおいて、仕様の誤検知が発生しにくい第１の現像カートリッジ１１Ａおよび第３の現像カートリッジ１１Ｃが装着されたときに、仕様の誤検知が発生しやすい第２の現像カートリッジ１１Ｂが装着されたときよりも低い現像バイアスを現像ローラ１５に印加するように構成する。これにより、第２の現像カートリッジ１１Ｂを第１の現像カートリッジ１１Ａまたは第３の現像カートリッジ１１Ｃと誤検知した場合に、トナーの消費量を低減して、第２の現像カートリッジ１１Ｂの最大の画像形成枚数を保証する。【選択図】なし
