IMAGE FORMATION APPARATUS AND IMAGE FORMING METHOD

摘要

An image formation apparatus includes: a first image formation unit including a first image carrier and a first charging member that charges the first image carrier, the first image formation unit using a first developer and; a second image formation unit including a second image carrier and a second charging member that charges the second image carrier, the second image formation unit using a second developer; and a controller that determines a first charging voltage correction amount for correcting a charging voltage to be applied to the first charging member according to an amount of usage of the first image carrier, and determines a second charging voltage correction amount for correcting a charging voltage to be applied to the second charging member according to an amount of usage of the second image carrier. The second charging voltage correction amount is larger than the first charging voltage correction amount.
