Abstract
An imaging system includes a photoreceptor including a surface to form a static latent image, a non-contact charging device being spaced apart from the photoreceptor, a power source to apply a voltage to the charging device, and a controller. The charging device charges an image-forming portion of the surface of the photoreceptor during an image-forming period and charges a non-image-forming portion of the surface of the photoreceptor during a non-image-forming period. The controller changes a signal parameter of the voltage to be applied by the power source during the non-image-forming period, in order to adjust a current flowing from the charging device to the photoreceptor.
