Abstract
An image forming apparatus using an electrophotographic process includes an image forming unit, a storage unit, and a control unit. The image forming unit performs monochrome printing and color printing. The storage unit stores print ratio data that relates to printing in the image forming unit is measured over time. The control unit separately performs correction of monochrome toner density and color toner density based on a predetermined first condition. If the first condition in the monochrome printing is met, the control unit performs correction of the monochrome toner density if a predetermined second condition concerning an amount of variation in the print ratio identified from the print ratio data is also met.

An image forming apparatus using an electrophotographic process comprising:
- an image forming unit configured to perform monochrome printing and color printing;
- a storage unit that stores print ratio data relating to printing in the image forming unit measured over time;
- and
- a control unit configured to separately perform correction of monochrome toner density and correction of color toner density based on a predetermined first condition, if the first condition in the monochrome printing is met, the control unit performs correction of the monochrome toner density if a predetermined second condition relating to an amount of variation in the print ratio identified from the print ratio data is met.
A method for performing image forming using an electrophotographic process comprising:
- performing monochrome printing and color printing;
- storing print ratio data relating to printing, measured over time;
- and
- separately performing correction of monochrome toner density and color toner density based on the use of a predetermined first condition, if the first condition in the monochrome printing is met and if a predetermined second condition concerning an amount of variation in the print ratio identified from the print ratio data is met, correction of the monochrome toner density is performed.
