摘要： A developer contamination measuring apparatus of a printer includes a first pipe portion having a first gap and a second pipe portion having a second gap, a light emitting unit radiating light to the first pipe portion and the second pipe portion, a light detecting unit detecting light reflected or transmitted from the first pipe portion and the second pipe portion to output first and second light receiving signals, respectively, and a developer contamination measuring unit controlling the light emitting unit, and calculating the degree of a contamination due to mixing of other developing materials with the developer from the first and the second light receiving signals. Thus, the degree of contamination of a developer mixed with other developing materials can be precisely calculated, and the developer can be replaced, when the calculated amount of contamination exceeds a predetermined allowable contamination level, to thereby prevent deterioration of print quality.
