<p><P>PROBLEM TO BE SOLVED: To provide a technique for suppressing the relative position of an electrifying device with respect to a body to be electrified from being changed before and after cleaning. <P>SOLUTION: The electrifying device includes: a movable member 84 which is moved in the rotation axis direction of the body to be electrified to clean a part constituting electrifying means, and returned to a standby position provided on one end side in the rotation axis direction after cleaning; a shaft 86 which applies a moving force for moving in the rotation axis direction to the movable member 84; a positioning member 88 which regulates the movement of the movable member 84 in a first direction which is a return direction to the standby position; and a first regulating member 861 which regulates the movement of the shaft 86 in a second direction which is a direction to the other end side in the rotation axis direction. The electrifying device has such a relation that a force in the second direction which acts on the shaft 86, when the movement of the movable member 84 is regulated by the positioning member 88 regardless of the application of the moving force by the shaft 86, and a force in the first direction which acts on the shaft 86 when the movement of the shaft 86 is regulated by the first regulating member 861 are attracted to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
