摘要： Disclosed is a device for measuring the density of an image in regard to a liquid test patch. The device has: a fan for drying a test patch by blowing air to the test patch disposed on at least one of a photosensitive medium, a photosensitive belt and printing paper; a sensor for projecting infrared light to the dried test patch and measuring the density of the test patch based on the reflected light of the infrared light reflected from the test patch; and an adjustment unit for adjusting the mixing ratio of a toner and a carrier in accordance with the measured density. The device measures the amount of light reflected from the dried liquid test patch, thus allowing the density of the image to be measured accurately.

摘要： A method and apparatus for measuring the color tone density of an image output from a multipass color printer consumes a minimum of time by using a test pattern that includes test patches for all of the developing units in the printer. The method includes developing a test pattern, which includes test patches for all developing units, on an organic photo conductor, measuring the color tone density of the developed test pattern, and adjusting developing variables according to the measured color tone density. Accordingly, it is possible to reduce the time required to measure the color tone density of an image output from a multipass color printer, using the test pattern.
