ABSTRACT:
A development device is provided with a development vessel, a toner box, a toner amount detection sensor, and a control section. The development vessel accommodates toner to be supplied to an electrostatic latent image on an image carrier. The toner box replenishes toner into the development vessel. The toner amount detection sensor detects an amount of toner accommodated in the development vessel. The control section calculates an amount of toner to be used during image formation based on density information of an image to be formed and controls an amount per unit of time for replenishing toner from the toner box to the development vessel based on the calculated amount of toner to be used and the amount of toner accommodated detected by the toner amount detection sensor.
