Image forming apparatus, method of determining amount of developer supply, and program of determining amount of developer supply

摘要

To provide a technology that can realize appropriate developer supply processing according to conditions within a developing unit by a simple method. In an image forming apparatus that visualizes an electrostatic latent image formed on a photoconductor with a developing unit, information on an amount of consumption of a developer in the developing unit is acquired, first developer supply information indicating an amount of developer to be supplied to the developing unit is calculated based on the acquired information, information on concentration of the developer contained within the developing unit is acquired, second developer supply information indicating an amount of developer to be supplied to the developing unit is calculated based on the acquired information, and information indicating an amount of developer to be supplied to the developing unit is determined based on the calculated first and second developer supply information.
