To provide a technique to accurately detect the amount of developer even when recycling a cartridge for an image forming apparatus with an electrical storage device attached to the cartridge.SOLUTION: A cartridge is attached to an image forming apparatus, and comprises: a developer housing chamber, a stirring member rotating to stir and convey developer; detection means having a detection member and detecting the amount of developer; and storage means. The housing chamber is provided on its opening with a sealing member. The detection means detects the amount of developer based on passage time corresponding to the time at which the developer conveyed by the stirring member passes the vicinity of the detection member. The storage means stores information on the correspondence between the passage time of developer and the amount of developer, and the correspondence information includes correspondence information when the cartridge is a new product and correspondence information when the cartridge is a recycled product.SELECTED DRAWING: Figure 9 【課題】画像形成装置のカートリッジに電気的記憶デバイスを取付けたままカートリッジをリサイクルする場合にも、精度良くトナー量を検知する技術を提供する。【解決手段】現像剤の収容室と、回転して現像剤を攪拌および搬送する攪拌部材と、検知部材を有し、現像剤の量を検知する検知手段と、記憶手段を備え、画像形成装置に取り付けられるカートリッジであって、収容室の開口部には封止部材が設けられ、検知手段は、攪拌部材により搬送される現像剤が検知部材の付近を通過する時間に対応する通過時間に基づいて現像剤の量を検知し、記憶手段は、現像剤の通過時間と現像剤の量との対応情報を記憶しており、対応情報には、カートリッジが新品の場合とリサイクル品の場合それぞれの対応情報が含まれる、カートリッジを用いる。【選択図】図９
