摘要： A fixing apparatus has first and second heating members and a current control unit which controls a number of waves and each of a first AC current to the first heating member and a second AC current to the second heating member in a positive-negative symmetrical pattern by a unit of predetermined number of half-waves. Regardless of a duty ratio of the first heating member and the second heating member, when the current control unit controls a number of waves so that the second AC current is larger than the first AC current in the first duty ratio, the current control unit controls the number of waves so that the first AC current is larger than the second AC current in a second duty ratio adjacent to the first duty ratio.

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.
