Abstract: A bandgap reference voltage generation system includes a common mode voltage generator, a bandgap reference voltage generation circuit, and a switch controller. The bandgap reference voltage generation circuit includes a plurality of transistors having source terminals respectively connected to drain terminals of a plurality of PMOS transistors. The switch controller provides a ground voltage to the bandgap reference voltage generation circuit in a first mode and a common mode voltage to the bandgap reference voltage generation circuit in a second mode. The bandgap reference voltage generation circuit causes the plurality of the transistors to operate in a linear region by providing the common mode voltage to gate electrodes of the plurality of the transistors in the first mode and a saturation region by providing the ground voltage to the gate electrodes of the plurality of the transistors in the second mode.

Abstract: An image forming apparatus includes an image carrier on which an electrostatic latent image is formed, where the image carrier may include an image carrier body having a hollowness and image carrier flanges, which are installed at both ends of the image carrier body. Each image carrier flange may include a blower fan integrally formed therewith, so that air outside of the image carrier body is moved from one end of the image carrier body, at which a drive gear is positioned, to the other end of the image carrier body as the image carrier rotates. Waste developer which may accumulate on the drive gear is reduced, thereby preventing the operational error of the image carrier and thus avoiding the degradation of the image quality.
