PROBLEM TO BE SOLVED: To enable a manual cleaning in image formation devices including a reciprocal drive mechanism 40 reciprocally driving a rectilinear movement member 31 in which a cleaning member 32 cleaning a detection face of a toner density detection unit 30 is fixed.SOLUTION: An image formation device comprises: an urging member 46 that urges a rectilinear movement member 31 from a maximum movement position side of a linear direction toward an original position side to thereby move the rectilinear movement member 31 to the original position; a motor 41 that has an output shaft; a rotation member 42 that is directly or indirectly connected to the output shaft of the motor 41 to rotate in conjunction to a rotating motion of the output shaft; and pressing part 43 that is fixed to the rotation member 42, and presses the rectilinear movement member 31 against urging force of the urging member 46 accompanied by a rotating motion of the rotation member 42 toward the maximum movement position side from the original position side, and stays away from the rectilinear movement member 31 accompanied by the rotating motion of the rotation member 42 after the rectilinear movement member 31 reaches the maximum movement position.SELECTED DRAWING: Figure 4 |
