    • A replaceable unit determination mechanism includes a detection mechanism which has a lever member which is arranged so that the lever member comes into contact with a claw-shaped member when a rotatable member is rotating. The detection mechanism generates a detection signal when the replaceable unit is placed at a predetermined position and stops generating the detection signal when the lever member comes into contact with the claw-shaped member after the replaceable unit is placed in the predetermined position. The determination mechanism also includes a determination part which determines that the replaceable unit is correctly placed in the predetermined position when the detection signal is supplied from the detection mechanism and which determines that the replaceable unit is a new replaceable unit when the detection mechanism stops generating the detection signal. The claw-shaped member is broken when the claw-shaped member comes into contact with the lever member of the detection mechanism.

    • A toner image fixing device includes a driven fixing roller drivingly connected to a driving source and a rotatably mounted follower fixing roller. The follower fixing roller is mounted on a movable supporting member which is mounted for free movement between a contacting position at which the follower fixing roller is kept in press contact with the driven fixing roller and a non-contacting or non-pressing position at which the follower fixing roller is kept out of press contact with the driven fixing roller. A press-contacting control mechanism selectively holds the movable supporting member at the contacting position and the non-contacting position. The press-contacting control mechanism includes a positioning member connected to the movable supporting member via a spring and an actuating device for selectively holding the positioning member at an operating position and a non-operating position. When the positioning member is moved to the operating position, the movable supporting member is moved to the contacting position via the spring. When the positioning member is moved to the non-operating position, the movable supporting member is moved to the non-operating position via the spring.
    • 调色剂图像定影装置包括驱动地连接到驱动源和可旋转地安装的从动定影辊的从动定影辊。 自动定影辊安装在可移动的支撑件上,可移动的支撑件被安装成在从动定影辊与从动定影辊保持压接的接触位置和非接触或非按压位置之间自由移动, 从动定影辊与被驱动的定影辊保持脱离压接。 压力接触控制机构选择性地将可动支撑构件保持在接触位置和非接触位置。 压力接触控制机构包括经由弹簧连接到可移动支撑构件的定位构件和用于选择性地将定位构件保持在操作位置和非操作位置的致动装置。 当定位构件移动到操作位置时,可移动支撑构件通过弹簧移动到接触位置。 当定位构件移动到非操作位置时,可移动支撑构件经由弹簧移动到非操作位置。
