摘要： An image forming apparatus includes: a toner image carrier which carries a toner image thereon; a recording medium selection information input section to which recording medium selection information is inputted to select a recording medium to which the toner image carried on the toner image carrier is transferred; a fog controller which sets a fog control parameter value to control a fogging level of the toner image carrier; and an image forming section which forms the toner image to be carried on the toner image carrier based on the fog control parameter set by the fog controller. The fog controller sets the fog control parameter value so that the fogging level of the toner image carrier when the recording medium selection information inputted corresponds to a coated sheet, is lower than that when the recording medium selection information inputted corresponds to a normal sheet.
