Abstract
A toner density estimating method for a two-component developer is provided. The toner density estimating method includes: sensing photo-reflectance of a test pattern having a plurality of grayscales formed by using toner; calculating a rate of change of the photo-reflectance according to the grayscales of the test pattern; and estimating a toner density based on the rate of change. Accordingly, it is possible to accurately estimate the toner density irrespective of the influence of changes in temperature, humidity, or other external factors.
