ABSTRACT:
An image forming device capable of distinguishing the type of paper, and a driving controlling method thereof. The an image forming device includes a paper conveyance path disposed in a body of the image forming device, to guide an upside and an underside of the paper which is conveyed from a paper feeding apparatus to an image forming portion; a feeding roller disposed in the paper conveyance path, to convey the paper from the paper feeding apparatus to the image forming portion; and a paper type distinguishing sensor disposed in the paper conveyance path upstream with respect to the feeding roller, to distinguish the type of the paper and output a distinguishing signal. Accordingly, before the paper enters into the image forming portion, the distinguishing signal is output from the paper type distinguishing sensor as the feeding roller is rotated in a reverse direction to align a front end of the paper in parallel with the feeding roller. Therefore, the printing speed of the image forming device is improved.
