Abstract

An image formation apparatus includes an image carrier and a toner carrier having a concave portion arrayed in a regular pattern on its surface. A latent image that is carried on the image carrier is developed by toner carried in the concave portion by applying a development voltage to the toner carrier. After the toner carrier has developed the latent image, at least one layer of toner remains in the concave portion.
