PROBLEM TO BE SOLVED: To provide an image carrier rotary driving mechanism for the image forming device capable of always stably obtaining the image with an excellent quality by restraining the change of rotary driving speed of the image carrier. SOLUTION: In the image carrier rotary driving mechanism for the image forming device transmitting rotation of a driving source to the image carrier, provided with a driving source rotary driving the image carrier provided with a potoconductive layer for a latent image forming by making an engaging part formed on a driving shaft tip part of the driving source engaged with a engage hole SFa formed on a flange SF provided on an end part of the image carrier, the mechanism is composed so as to clamp engaging part formed on the driving shaft tip end of the driving source by plural screws (binding body) S1 to S3, and making the screws S1 to S3 radially screw coupled to the flange SF with the center at the engage hole SFa. In such a manner, since the engaging part on the driving shaft tip part of the driving source is clamped by the screws S1 to 53, the engagement between the engaging part of the driving shaft and the engaging hole SFa and the flange SF is prevented from the occurrence of the play, the rotary speed fluctuation is restrained, and the image with the excellent quality can be always stably obtained. |
