摘要： An image forming apparatus includes an application unit that applies to a holding unit a voltage that generates a potential difference between the holding unit and a photoconductor member such that a toner image is developed on the photoconductor member, the potential difference causing toner included in a two-component developer, held by the holding unit, to transfer from the holding unit to the photoconductor member, and a controller that controls the application unit, subsequent to an expiration of an image quality assurance period throughout which a predetermined image quality is assured, such that the potential of the holding unit is decreased in step with wear of the photoconductor member.
