    摘要: The image forming apparatus includes an image processing section that converts image data into pixel data, an image forming section that forms a toner image based on the pixel data, and a fixing section that fixes the toner image to the recording material by heating the recording material with the toner image formed thereon while conveying the recording material through a nip portion. The image processing section divides the pixel data corresponding to one recording material into a plurality of areas each formed of a predetermined number of pixels and acquires density information on some of the pixels within each of the areas as representative values. The fixing section carries out a process of fixing the toner image for which the density information has been acquired, under a fixing condition according to a maximum value of the representative values.

    摘要: An image heating apparatus has a heating member, a flexible sleeve, a guide member, a flange member, and a pressure member forming a nip part to nip and convey the heating member and the recording material through the sleeve. In this structure, in a recording material movement direction, a sliding-rubbing part of the flange member on a downstream side of the nip part has a shape to project the sleeve toward the downstream side. Alternately, the guide member may have a plurality of ribs on both an upstream side and downstream side of the nip.

    摘要: A heat fixing apparatus, in which a recording material, with an unfixed image passes through a fixing nip formed by a fixing member and a pressurizing member, has an electro-conductive member to be in contact with the recording material disposed downstream of the fixing nip with respect to the recording material conveying direction, wherein a bias voltage is applied to at least one of the fixing member and the electro-conductive member. As recording materials are consecutively fed, the bias voltage applied while the recording materials pass through the fixing nip portion is gradually decreased in accordance with the number of heated recording materials. Thus, smeared image trailing edge upon fixing is prevented from occurring, and the amount of toner adhering to the surface of the fixing member or the surface of the pressurizing member is reduced, so that image errors such as toner contamination are prevented from occurring.
