<P>PROBLEM TO BE SOLVED: To provide a printing device capable of reducing the difference in conveyance speed among a plurality of conveyance parts. Ž<P>SOLUTION: In this printing device, all the effective radii of three rollers being driving rollers, namely, the feeding roller 16, the intermediate roller 21, and the belt driving roller 25 (hereinafter referred to as "the driving rollers 16, 21, 25") are set to be the same so that speed at which a printing medium P is fed in the direction of conveyance (hereinafter referred to as "the conveyance speed") becomes the same, and these three rollers are rotated and driven at the same rotational speed (angular velocity). However, the conveyance speed is fluctuated depending on eccentricity of the center of rotation of the driving rollers 16, 21, 25, and difference in the conveyance speed among the driving rollers 16, 21, 25 occurs due to the fluctuation of this speed. For this reason, these three driving rollers 16, 21, 25 are arranged in such a way that respective phases in the fluctuation of speed agree. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
