15. The apparatus of claim 12, wherein a weight ratio of toner with respect to the developing agent in the agitation region is maintained to be within a predetermined percentage of a predetermined reference weight ratio.
16. The apparatus of claim 15, wherein said predetermined percentage is 120%.
17. The apparatus of claim 15, wherein the predetermined reference weight ratio is less than 10%.
18. The apparatus of claim 15, wherein the accumulated printing amount of the developing unit is set, and the reference weight ratio is set based on said accumulated printing amount.
19. The method of claim 15, wherein if the accumulated printing amount is increased, the reference weight ratio is also increased.
20. The apparatus of claim 12, wherein the developing unit compares a weight ratio of the toner with respect to the developing agent in the agitation region with a predetermined reference weight ratio, and if the weight ratio of the toner is less than the reference weight ratio, supplies the toner to the agitation region, and if the weight ratio of the toner is not less than the reference weight ratio, stops the supply of toner to the agitation region, and
wherein if the weight ratio of the toner with respect to the developing agent in the agitation region after the counting is performed is greater than 120% of the reference weight ratio, the developing unit compares the weight ratio of the toner with respect to the developing agent in the agitation region with the predetermined reference weight ratio.
