Abstract
An image forming apparatus includes a correction amount calculator, a fluidity measuring unit, and an external additive amount calculator. The correction amount calculator calculates a correction amount of fluidity to correct the fluidity of a two-component developer. The fluidity measuring unit measures the fluidity of the two-component developer. The external additive amount calculator corrects the measured fluidity on the basis of the correction amount of fluidity, calculates the amount of an external additive of a toner from the corrected fluidity of the two-component developer, and determines the state of the external additive.
