Abstract:
According to an embodiment of the invention, degradation of carrier in a case is detected from the number of rotations of a developing roller. A predetermined quantity of carrier is replenished every time the developing roller reaches a predetermined number of rotations. An excess developer caused by an increase in bulk through carrier replenishment is discharged from a developer discharge port. The degraded old carrier in the case is replaced by new carrier little by little.
