Patent ID: 7042482

Claim:
An image processing apparatus, comprising: an exposing device for exposing an image forming material so as to form a latent image on the image forming material based on image data; a thermal developing device for developing and visualizing the latent image on the exposed image forming material so as to form an image; a measuring device for measuring an image density of the image on the developed image forming material; a calibrating device tor forming a table to define a relationship between an image signal and image density based on a plurality of different test image data and corresponding measured-image densities; a counting device for counting a number of the image forming materaials developed within a predetermined time; and a controlling device for controlling the exposing device, the thermal developing device, the measuring device, the calibrating device and the counting device; wherein the controlling device prevents formation of the table for a predetermined time when the number of the developed image forming materials counted by the counted device is more than a predetermined number.
