  • Patent number: 6898387
    Abstract: An image processing apparatus is capable of determining the optimal fixing condition taking the local toner distribution (toner density) into consideration from image data. The toner amount is obtained for a local area formed by a marked pixel and the surrounding pixels per color component signal, and the toner amount of each local area is added. Further, over the image data entirely, the toner amount of local area is worked out in plural local areas. Then, a toner amount that indicates the maximum value is acquired from the toner amount of plural local areas. On the bases of the toner amount in the local area that indicates the maximum value and the kind of sheet on which toner is fixed, the fixing speed is controlled optimally.
