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.

Claim (Index 1):
An image formation apparatus comprising:\n an image carrier rotatable in a first rotating direction and configured to carry a latent image on a surface; a charging member disposed to face the image carrier at a first position and configured to charge the surface of the image carrier; a developer carrier disposed to face the image carrier at a second position and configured to carry a developer used to develop the latent image; 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, wherein the controller in a first period, performs control to apply the charge voltage and the development voltage to the charging member and the developer carrier respectively while rotating the image carrier in the first rotating direction such that the controller sets an absolute value of a voltage difference between a direct-current (DC) component of the charge voltage and a direct-current (DC) component of the development voltage to a first value, to develop the latent image, and in a second period after the first period, performs control to apply the charge voltage and the development voltage to the charging member and the developer carrier respectively while rotating the image carrier in the first rotating direction such that the controller sets the absolute value of the voltage difference to a second value smaller than the first value.
