Abstract
An image formation apparatus according to an embodiment includes: an image carrier; a charging member facing the image carrier; a developer carrier facing the image carrier; and a controller that controls a rotating operation of the image carrier, application of a charge voltage to the charging member, and application of a development voltage to the developer carrier. In a first period, the controller sets an absolute value of a voltage difference between a DC component of the charge voltage and a DC component of the development voltage to a first value to develop a latent image on the image carrier. In a second period after the first period, the controller sets the absolute value of the voltage difference to a second value smaller than the first value.
