Image forming apparatus and method of the same

An image forming apparatus and a method thereof are provide to improve product competitiveness through miniaturization of the image forming apparatus because the image forming apparatus doesn't need an apparatus which conducts the entire drum surface in the image forming apparatus and an apparatus for exposing the drum surface. One pole plate of a capacitor is a part of plural cells. An electrostatic latent image is self-generated on a surface by conducting a drum considering print data for printing one pole plate(110). A developing unit generates a developing image by developing the electrostatic latent image(120). A thermal imaging unit thermal-images the generated developing image on a print medium(130). A fusing unit fuses the thermal-imaged developing image on the print medium(140).
