Abstract
An image-forming device can include an image acquiring unit that acquires image data, an image forming unit that forms an image based on the image data, a determining unit that determines whether the image data includes a part having density greater than or equal to a prescribed density, and a controller. The image forming unit can include a developing roller, a supply roller for supplying developer to the developing roller, and a bias applying unit that applies first and second voltages between the developing roller and the supply roller in first and second modes, respectively. The controller can control the bias applying unit to apply one of the first and second voltages when the determining unit determines whether the image data includes the part having density greater than or equal to a prescribed density.
