Claims

[Claims for Utility Model Registration] 1. A blade strain measuring device for measuring distortion of a cleaning blade acting on an image bearing means, comprising: a pseudo member having a surface substantially corresponding to the surface shape of at least a part of the image bearing means; a blade support mechanism that supports the cleaning blade so as to be movable in directions approaching and away from the dummy member and causes its tip to act on the surface of the dummy member at a predetermined angle at the start of measurement; and a blade support mechanism that biases the cleaning blade. a biasing means for pressing the tip of the cleaning blade against the surface of the pseudo member with a predetermined pressing force; a displacement amplifying mechanism for enlarging the amount of strain of the cleaning blade; A blade strain measuring device comprising: a displacement measuring means for measuring the amount of displacement; and a blade strain measuring device. 2. The blade strain measuring device according to claim 1, further comprising contact display means that is electrically connected when the measuring section of the displacement measuring means comes into contact with the detected section provided on the displacement magnification mechanism to notify that the two have come into contact. .
