Toner Calculation in an Image Forming Device
First Claim
1. An image forming apparatus that consumes toner to form an image, the apparatus comprising:
- a first calculation portion that calculates a toner consumption by a first calculation method;
a second calculation portion that calculates the toner consumption by a second calculation method according to a predetermined calculation formula after a predetermined switching criterion is satisfied; and
a third calculation portion that calculates a value of a parameter in the predetermined calculation formula of the second calculation method based on the toner consumption calculated by the first calculation method.
