ABSTRACT:
An image forming apparatus and a method of preventing a carrier from adhering to a photosensitive drum are provided. The image forming apparatus includes a photosensitive drum on which an electrostatic latent image is formed by an exposure unit, a main motor which rotates the photosensitive drum, an eraser unit which removes a potential charged on the photosensitive drum, and a controller which controls the eraser unit to remove a potential of the photosensitive drum while the photosensitive drum rotates due to an inertial force after the main motor stops rotating.
