PURPOSE: To provide an image forming device where the color slurring of a color image is not caused even when temperature is changed, and where a frame and a pulley are formed of a material having such a linear expansion coefficient that the change of an exposing position and the change of carrying speed which are caused by temperature change are cancelled. CONSTITUTION: This image forming device is provided with plural exposing means 4, plural units 1 consisting of a charging means 3, an image forming body 2 and a developing means 5, a carrying means 11 carrying a recording medium 8 by the rotation of plural rotating bodies 10, and plural transferring means 6; and a multicolor image is recorded on a recording medium 8 with the toners of different colors by each unit 1. The device is provided with a 1st frame 13 supporting the plural exposing means 4, and a 2nd frame 14 supporting the plural units 1; and the 1st/2nd frames 13 and 14 and the rotating body 10 are formed of the material having such a linear expansion coefficient that the change of the position of the image forming body 2, the change of a position for irradiating the image forming body 2, and the change of the carrying speed of the carrying means 11 which are caused by the temperature change are cancelled. |
