An image forming apparatus capable of improving transfer properties, and a method for improving the transfer properties are provided by the invention. According to the method of the present invention, a surface of a photoconductive medium is electrified by applying a voltage to the photoconductive medium. An electrostatic latent image is formed on the surface of the electrified photoconductive medium. A visible image is formed by supplying toner to the surface of the photoconductive medium whereon the electrostatic latent image is formed, and the visible image of the photoconductive medium is transferred onto a paper. In the transferring step, the resistance of the paper is measured, and the image transfer is performed by maintaining a current electrifying potential if the resistance of the paper is lower than a predetermined value and lowering the current electrifying potential of the photoconductive drum if equal to or greater than a predetermined value. Accordingly, the electrifying potential of the photoconductive medium and the developing voltage can be decreased without a dedicated charge removing unit. Therefore, electric charge on the high-resistance paper can be easily removed, and a transfer area can be broadened. Consequently, a phenomenon such as image scattering can be prevented.
