Abstract
An image forming system of an electrophotographic printer. The system includes a photosensitive body on which an electrostatic latent image is formed, a developing unit which develops the electrostatic latent image with a developer, a transfer body onto which the developed image is transferred, a first image charging unit which charges the image so as to increase an electric adhesive force of the image transferred onto the transfer body, a second image charging unit which charges the image so as to reduce the electric adhesive force of the image transferred onto the transfer body in the rear of the first image charging unit, and a transfer unit which transfers the image passing through the first and second image charging units onto paper. When the image is transferred onto the transfer body, the first image charging unit increases the electric adhesive force of the image and prevents the image from dispersing, and the second image charging unit reduces the adhesive force suitable for transfer just before the image is transferred onto the paper, and thus the clear image can be maintained, and a transfer efficiency can be improved.
