Abstract:
1. An image formation device for forming an image by an electrophotographic process forming a latent image on a surface of a photoreceptor charged by a charge member, attaching a developer to the latent image on the surface of the photoreceptor to form a developer image, and then transferring the developer image from the photoreceptor to a medium, the image formation device comprising: a charge voltage controller configured to control an application charge voltage to be applied to the charge member; a transfer voltage controller configured to control a transfer voltage to be applied to a transfer member; a charge current detector configured to detect a charge current flowing through the charge member; and a controller configured to determine the application charge voltage according to the application charge voltage and the detected charge current both detected when the transfer voltage controller applies a predetermined transfer voltage, wherein the controller is configured to:
