摘要： A cartridge includes; a first gear rotatably provided at the casing; a second gear including a toothed portion and a toothless portion; and a storing portion configured to store the second gear. The second gear includes an arm that is flexible and extends substantially along a peripheral direction of the second gear. An inner peripheral surface of the storing portion includes a bulging portion that bulges inward in a radial direction. The bulging portion has a peak portion closest to a rotation center of the second gear. The arm is deflected while the arm contacts the bulging portion. The deflection of the arm is changed from an increasing tendency to a decreasing tendency at the peak portion as a base point. The toothed portion of the second gear is separated from the first gear when the end portion of the arm has crossed over the peak portion.

摘要： A light traveling permissible portion and a light traveling blocking portion are alternately disposed in a specification detecting and agitator driving gear such that a detection portion detects information corresponding to the maximum image formation sheet number. When the developer cartridge is new, a new/used cartridge detecting gear restricts transmission of the aforementioned information from the specification detecting and agitator driving gear to the detection portion for a predetermined time t, thereby detecting whether the developer cartridge is new or the used. The detection portion detects whether the developer cartridge is mounted based on whether there is the detection light reflected from the light traveling permissible portion.

摘要翻译： 在规格检测和搅拌器驱动齿轮中交替地设置有光行进许可部分和光行进阻挡部分，使得检测部分检测与最大图像形成纸张号相对应的信息。 当显影剂盒是新的时，新的/用过的盒式磁带检测装置将上述信息从规格检测和搅拌器驱动齿轮传送到检测部分预定时间t，从而检测显影剂盒是新的还是使用的。 基于是否存在从光行进许可部反射的检测光，检测部检测是否安装了显影剂盒。
