摘要： A rotation member driving device and an image forming apparatus using the same are provided. Without enlarging the device and increasing the cost, by reducing a speed variation generated during one rotation of a rotation member such as an image holding member or an intermediate transfer member, the distortion or color misregistration of an image formed on or transferred onto the rotation member is reduced and a high quality image can be formed. In the rotation member driving device for rotating and driving the rotation member for image formation by a gear attached thereto, a relation between a phase of eccentricity of the rotation member and a phase of a cumulative pitch error in a rotation direction of the gear is set so that a variation of a surface speed due to the eccentricity of the rotation member is restrained from appearing on the image.
