Abstract: An image forming apparatus including a rotating photosensitive drum, a cleaning blade having a cleaning edge part which makes contact with an outer surface of the photosensitive drum along an axial direction of the photosensitive drum and a bracket having a contact surface where the bracket makes contact with the cleaning blade to support the cleaning blade, the width of the contact surface between the bracket and the cleaning blade being maximum at the center part of the cleaning blade and gradually decreasing from the center part to opposite end sides of the cleaning blade. Thus, a cartridge for an image forming apparatus having a cleaning blade and a bracket prevents poor quality in a cleaning surface of a photosensitive drum and has improved durability.

Abstract: A method of revising a medium resistance to determine a transfer voltage and an image forming device to perform the same. The method includes supplying a medium recognition voltage to recognize a print medium, and reading medium resistances according to a predetermined reading cycle, calculating an estimated medium resistance based on the read medium resistances, by referring to a pattern of medium resistance in an interval between a time at which the medium recognizing voltage is supplied and a predetermined stabilizing time, and determining a medium resistance to be applied when a transfer voltage is supplied, by comparing the calculated estimated medium resistance with the read medium resistances obtained after the predetermined stabilizing time.
