Abstract
An image forming apparatus includes: a latent image carrier; an image forming unit configured to form, on the latent image carrier, a toner image using a developer including a toner and a lubricating external additive charged with an opposite polarity to a charge polarity of the toner; a transfer device configured to electrostatically transfer, at a transfer position, the toner image formed by the image forming unit to a transfer medium; and a cleaning device configured to remove the toner remaining on the latent image carrier after passing the transfer position. The transfer device is configured to control a transfer voltage applied at the transfer position, based on an area ratio of an image to be printed.
