An image forming apparatus is provided in which changes in speed of an intermediate transfer body and a photosensitive body are suppressed and thereby a high quality image without density unevenness, color misalignment, a smear or the like can be formed, and which does not require a larger size in structure, increase in power consumption, a higher degree of complexity and the like. A rubbing contact member, high viscosity damper, magnet, or electromagnetic brake imposes a constant rotation load on the intermediate transfer body. Impulsive and constant changes in speed of the intermediate transfer body and the photosensitive body are suppressed even if changes arise in torque load on the intermediate transfer body and the photosensitive body.
