IMAGE CHARACTERISTIC MEASURING DEVICE AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an image characteristic measurement device able to correctly measure the color of an image formed by an image forming apparatus.

SOLUTION: The image characteristic measuring device comprises: first light emitting means 101 for emitting light to a predetermined area of an image on an image carrier that is a measurement object; first imaging means 103 for condensing light reflected from the measurement object to which light has been emitted; area splitting means 104 installed in the position where an imaging relation is substantially established with the measurement object and used for splitting an area by an aperture line; second imaging means 105 for condensing reflected light whose area has been split; spectroscopic means 106 for subjecting area-split light passed through the aperture line to spectroscopic operation so that diffraction images do not overlap; array state light-receiving means 107 for receiving area-split light from each aperture; second light emitting means 111 for emitting light between the aperture line and the second imaging means from above; and reflecting means for reflecting light from the second light emitting means toward the aperture line. The distance between the aperture line and second light emitting means via reflecting means and the distance between the aperture line and the incident pupil of the second imaging means are the same.
