    • A connector receives first and second differential signals. First and second signal lines are connected to the connector, and transmit the first and second differential signals, respectively. First and second differential capacitors have first and second end terminals to remove noise components of the first and second differential signals. Each of the first end terminals is connected to ground potential. The second end terminals are connected to the first and second differential lines, respectively. A differential resistor is connected to the first and second signal lines to remove the noise components of the first and second differential signals. A receiving part is connected to the first and second signal lines to receive the first and second differential signals through the differential resistor and the first and second differential capacitors.

    • 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.
