摘要： During printing on a thick paper, a Scorotron charger disposed upstream of a developing roller in a drum rotational direction charges a photosensitive drum to about 1000 V. Then a transfer roller disposed downstream of the developing roller lowers the potential to about 80 V. The transfer bias is turned off at the end of printing at T1 and does not lower the surface potential after this. When the surface of the drum opposite the transfer roller reaches a position opposite the Scorotron charger at T2, a DC motor and a charging bias are turned off. The surface potential of the drum that passes opposite the developing roller remains at about 400 V and is higher than developing roller potential until the photosensitive drum comes to a complete stop after idling at T3. This prevents the developing agent from adhering to the photosensitive drum.

摘要翻译： 在厚纸上打印时，设置在鼓旋转方向上的显影辊上游的Scorotron充电器将感光鼓充电至约1000V。然后，设置在显影辊下游的转印辊将电位降至约80V。转印 偏压在T 1打印结束时关闭，此后不会降低表面电位。 当转鼓对面的表面在T 2处到达与Scorotron充电器相对的位置时，DC电机和充电偏压被关闭。 与显影辊相对的鼓的表面电位保持在约400V，并高于显影辊电位，直到感光鼓在T 3空转之后完全停止。 这防止显影剂粘附到感光鼓上。

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： The invention describes an image forming apparatus having a cartridge configured to be removably attached to a main body. The cartridge has a rotational body positioned within the cartridge and an extension portion protruding outward from the rotational body in an axial direction. The device body has a main body, which has a driving member that rotates the rotational body and the extension portion, a detecting unit for detecting a movement of the extension portion, and a determining unit for determining a type of the developer cartridge using either a time elapsed between a time in which the driving member begins driving the rotational body and a time in which the detecting unit detects the movement of the extension portion, or a drive amount of the drive device occurring during an elapsed time.

摘要： A cartridge includes an engagement gear which includes a first engaging portion and is configured to selectively rotate. The cartridge also includes a rotational body which includes a second engaging portion, and a center axis of the rotational body is aligned with a center axis of the engagement gear. Moreover, the cartridge includes an extension portion which is positioned offset from a center of rotation of the rotational body. The engagement gear and the rotational body are configured to selectively be positioned in one of a first state in which the second engaging portion and the first engaging portion are separated from each other, and a second state in which the second engaging portion engages the first engaging portion. The rotational body is configured to rotate with the engagement gear when the engagement gear rotates and the engagement gear and the rotational body are in the second state.

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 used. The detection portion detects whether the developer cartridge is mounted based on whether the detection light reflects from the light traveling permissible portion.
