The image forming apparatus includes a photosensitive drum, developer bearing members to develop a latent image formed on the photosensitive drum into a toner image while bearing developer, a secondary transfer roller to transfer the toner image to a sheet, an operation apparatus to which smoothness of the sheet having the toner image transferred, and a CPU which controls to decrease fog elimination potential difference between non-image portion potential of the photosensitive drum and direct current component potential of bias applied to developer bearing members in a case that smoothness inputted to the operation apparatus is information that the smoothness of the sheet having the toner image formed is equal to or higher than a predetermined smoothness as compared to a case of being lower than the predetermined smoothness.
