Claims

[Claims for utility model registration] (1) A first member and a second member that contacts the first member.
Peeling means cleaning for cleaning dirt on the peeling means in an apparatus comprising a member and a peeling means capable of breaking the contact between the first member and the second member at a predetermined position and movable from the predetermined position. In the mechanism, when the peeling means is located at the predetermined position, the pair of cleaning members are separated from the peeling means, and in the process of moving the peeling means from the predetermined position to another position, the pair of cleaning members are separated from the peeling means. A peeling means cleaning mechanism comprising: a control mechanism for cleaning a member by bringing the member into contact with the peeling means while sandwiching the member from both sides thereof. (2) The first member is a fixing roller, the second member is a transfer member, and the peeling means is attached to a frame that can be detached from an apparatus main body incorporating the fixing roller, and when the frame is detached, The pair of cleaning members are attached to the main body of the apparatus, and when the peeling claw is in the predetermined position, the pair of cleaning members are opened above and below, on the left and right sides, or on both sides of the front and back of the peeling claw. The control mechanism includes a biasing means for biasing the cleaning member to close, and a biasing means for biasing the cleaning member to close, and a cleaning member that closes in response to the detachment operation of the frame and comes into contact with the peeling claw. means attached to the cleaning member, which directly or indirectly applies force to the cleaning member by movement of the frame in the process of connecting the frame to the main body of the apparatus, and resists the force of the urging means. and an action member that reduces or eliminates the force applied to the cleaning member when the frame is removed from the main body of the apparatus by opening the cleaning member. Means cleaning mechanism. (3) Before the tip of the stripping claw reaches the position where the closed cleaning member is present, the action member opens the cleaning member, and the tip of the stripping claw leaves the location where the cleaning member is present. 3. A stripping means cleaning mechanism as claimed in claim 2, characterized in that before said actuating member closes its cleaning member. (4) The first member is a fixing roller, the second member is a transfer paper, and the peeling means is attached to a frame that is detachable from the apparatus main body in which the fixing roller is installed, and the peeling means is attached to a frame that is detachable from the apparatus main body in which the fixing roller is installed, and the pair of cleaning members are attached to the apparatus main body side, and are located away from the peeling claw when the peeling claw is at the predetermined position;
In addition, the control mechanism includes a biasing means for biasing the cleaning member toward the predetermined position and a biasing means for biasing the cleaning member toward the predetermined position; The attached means directly or indirectly applies a force to the cleaning member by movement of the frame in the process of connecting the frame to the main body of the apparatus, and resists the force of the urging means. and an action member that reduces or eliminates the force applied to the cleaning member when the frame is removed from the device main body by moving the cleaning member away from the predetermined position. Item 1. Peeling means cleaning mechanism. (5) Before the tip of the stripping claw reaches the predetermined position, the action member separates the cleaning member from the predetermined position, and before the tip of the stripping claw leaves the location where the cleaning member is present. 5. The peeling means cleaning mechanism according to claim 4, wherein the operating member brings the cleaning member close to the predetermined position and brings it into contact with the peeling claw.
