    • A sheet size detecting apparatus having a first arm moved by a moving sheet contacting therewith, a second arm moved by the moving sheet contacting therewith, the second arm being disposed at a location differing from that of the first arm in a direction orthogonal to the movement direction of the sheet, and a sensor, wherein the output level of the sensor when only one of the first arm and the second arm has been moved is the same as the output level thereof when neither of the first arm and the second arm is moved, and the output level of the sensor when both of the first arm and the second arm have been moved differs from the output level thereof when neither of the first arm and the second arm is not moved. Thereby, the cost can be suppressed and yet, the wrong detection of the sheet size can be prevented.

    • An image forming apparatus has a sheet size detecting unit with first and second arms each moved by contact with a moving sheet, the arms disposed at differing locations in a direction orthogonal to sheet movement. An actuator which acts on the sensor is not moved when only one arm is moved by sheet contact, but is moved when both arms are moved by sheet contact so that the sensor output level when only one arm is moved is the same as when neither arm is moved, and the output level of the sensor when both of arms have moved differs from when neither arm moves. The first and second arms have first and second regulating portions, respectively, for regulating actuator movement, and the actuator is moved only when both regulating portions are moved from contact of both arms with the moving sheet.
    • 图像形成装置具有纸张尺寸检测单元,其具有通过与移动片接触而移动的第一和第二臂,所述臂设置在与片材移动正交的方向上的不同位置处。 当只有一个臂通过片接触移动时,作用在传感器上的致动器不会移动,但是当两个臂通过片接触移动时移动,使得当仅一个臂移动时的传感器输出电平与当双臂 并且当两个臂都移动时传感器的输出水平不同于两臂都不移动。 第一臂和第二臂分别具有用于调节致动器运动的第一和第二调节部分,并且仅当两个调节部分从两个臂与移动片的接触移动时,致动器才移动。

    • An image forming apparatus includes a rotatable member-to-be-cleaned having elasticity; a cleaning member, having elasticity, for removing a deposited matter deposited on the member-to-be-cleaned; and a supporting portion for supporting the cleaning member so that the cleaning member swings around a swing fulcrum. The swing fulcrum of the supporting portion is provided so that a force exerted from the member-to-be-cleaned onto the cleaning member with respect to a direction along a tangential line where the cleaning member and the member-to-be-cleaned contact each other during movement of the member-to-be-cleaned has a vector component in a direction in which the cleaning member is moved away from the member-to-be-cleaned.
