摘要： PURPOSE: An image forming apparatus, a method for controlling the same, a developing apparatus and a memory medium are provided to detect a residual amount of developer with high accuracy and detect a utilized amount of the developing apparatus from the start of use. CONSTITUTION: An image forming apparatus has a developing apparatus(151) for developing a latent image on an image bearing member corresponding to image information. The developing apparatus is detachably attached to the image forming apparatus. The image forming apparatus includes the first detection device for detecting an amount of developer in the developing apparatus, the second detection device for detecting a utilized amount of the developer in the developing apparatus based on the image information, and a processing unit(241) for judging a utilized amount level of the developing apparatus based on results of detection of the first detection device and the second detection device. The processing unit judges the utilized amount level of the developing apparatus using the result of detection of the first detection device and the result of detection of the second detection device until the result of detection of the first detection device reaches a predetermined value, and judges the utilized amount level of the developing apparatus using the result of detection of the first detection device after the result of detection of the first detection device has reached the predetermined value.
摘要翻译：目的：提供一种图像形成装置，其控制方法，显影装置和存储介质，以高精度检测显影剂的残留量，并从使用开始检测显影装置的使用量。构成：图像形成装置具有用于在与图像信息对应的图像承载部件上显影潜像的显影装置（151）。显影装置可拆卸地附接到图像形成装置。图像形成装置包括用于检测显影装置中的显影剂量的第一检测装置，用于基于图像信息检测显影装置中的显影剂的利用量的第二检测装置，以及用于基于第一检测装置和第二检测装置的检测结果判断显影装置的利用量水平。处理单元使用第一检测装置的检测结果和第二检测装置的检测结果来判断显影装置的利用量水平，直到第一检测装置的检测结果达到预定值，并且判断在第一检测装置的检测结果之后，使用检测到第一检测装置的结果的显影装置的利用量水平已达到预定值。
