ABSTRACT:
An image forming apparatus includes an image bearing body and a developer bearing body. A transferring section transfers, onto a medium, a developer image formed on the image bearing body by development of the latent image. A voltage applying section alternately applies, to the developer bearing body, a first voltage for making the developer move from the developer bearing body toward the image bearing body in order to develop the latent image, and a second voltage for making the developer move from the image bearing body toward the developer bearing body. An image darkness adjusting section adjusts a darkness of the image to be formed on the medium by changing only the second voltage.
