An image forming apparatus of the present invention includes a latent image forming unit to form an electrostatic latent image on a charged image carrier, a developing device to form a developer image by developing the electrostatic latent image formed on the image carrier by a developer and a charge removing unit to discharge the image carrier before transferring the developer image and reduce the electrostatic adsorbing power of the developer image to the image carrier. The charge removing unit includes a charge removing light source to apply the charge removing light to the image carrier and the developer image and the charge removing charger to remove the charge by discharging the image carrier and able to control the discharge output. The charge removing unit is controlled to be adjusted a charge removing capacity.
