Abstract: An image forming apparatus is configured to reduce a velocity fluctuation of a rotating body by reducing the AC velocity component of the rotating body. The image forming apparatus may include an image bearing body with a surface on which a toner image is formed; a driving motor configured to drive the image bearing body according to an input signal; and a controller configured to control the driving motor to output a motor output velocity at a period equal to that of an AC velocity component of the image bearing body. A velocity control method for the rotating body includes sampling a continuous motor input signal at a period equal to that of an AC velocity component of a rotating velocity of the rotating body. The sampled signal is transmitted to a driving motor that drives the rotating body, which is driven based upon the discrete motor input signal.

Abstract: A wet-type image forming apparatus includes an intermediate transfer medium for receiving images which are formed in a plurality of photosensitive media and overlapped thereon to form an image and transferring the image to a print medium. The intermediate transfer medium runs along a predetermined path. A drying unit heats the intermediate transfer medium to evaporate part of carrier included in the image on the intermediate transfer medium before the image is transferred onto the print medium. A cooling unit cools the heated intermediate transfer medium after the image is transferred onto the print medium by making the intermediate transfer medium directly contact a coolant.
