An image formation apparatus includes a containing section that contains a developer and that has an opening at which a developer carrier is exposed. The developer carrier rotates at a faster first speed or a slower second speed. When a detected height of developer in the containing section is at a replenishment start level and the developer carrier is rotating at the first speed, a replenishing member replenishes developer until the height of the developer reaches a replenishment end level. When the detected height of developer is at the replenishment start level and the developer carrier is rotating at the second speed, the developer is replenished by a predetermined amount.
