Abstract
An image forming apparatus is configured to determine that a toner container was replaced during power off in a case where identification information acquired from a toner container and identification information stored in a nonvolatile memory do not match each other when power is turned on. In a case where the replaced toner container does not satisfy a replacement condition and does not contain a black toner, the image forming apparatus permits the execution of printing in a monochrome print mode, and suspends the execution of printing in the color print mode.
