ABSTRACT:
A method for measuring an amount of toner on a recording medium that can accurately measure the toner amount. Information on the recording medium to which the toner is fixed is acquired. The toner fixed to the recording medium is irradiated with laser light. A light intensity distribution of reflected light of the laser light is detected. The amount of the toner on the recording medium is calculated on the basis of the acquired recording medium information and the detected light intensity distribution.
