(54) Image forming device having paper dust removing units


(57) An image forming device capable of sufficiently removing paper dusts on a sheet thereby providing high quality image. A sheet transport path (38) is defined between a sheet supply section (7) provided with a separation pad (13) and a sheet supply roller (12) and an image forming section (5). Along the sheet supply section (7), at least a first paper dust removing roller (9b) having a width slightly greater than the width of the separation pad (13) and a second paper dust removing roller (10b) having a width slightly greater than the sheet width are disposed. Paper dusts generated upon friction against the separation pad (13) are removed by the first paper dust removing roller (9b), and paper dusts spreading over entire surface of the sheet are removed by the second paper dust removing roller (10b).
