PROBLEM TO BE SOLVED: To exactly obtain the deviated origin point of toner and automatically obtain charged quantity distribution in a measuring device of charged quantity distribution of toner which obtains charged quantity distribution from deviated displacement due to electric field. SOLUTION: In the measuring device of charged quantity distribution of toner for obtaining charged quantity distribution from deviated displacement, by impressing electric field to the toner in air flow with a uniform velocity, the direction of the electric field is varied during measurement and an image with overlapping of a plurality of different toner images is gained on one collector. By this method, the deviated origin point of the toner is obtained. Then, by applying a series of image processing to the toner image, the charged quantity distribution of toner can be obtained.
