摘要： An image forming apparatus includes an input unit for inputting image data and a converter for converting the input image data into dot information. An image forming circuit controls a scan optical system on the basis of the dot information to form an image. The converter converts the image data into dot information having a screen angle by repeatedly using a predetermined threshold matrix so that the dot information appears preferentially in a sub-scan direction, perpendicular to the main-scan direction of the scan optical system. In the threshold matrix, threshold values are arranged so that their levels increase preferentially in the sub-scan direction.

摘要： In an image heating apparatus, outer peripheral surfaces of two endless belts are held in contact with each other to form a nip portion, and a recording material bearing a toner image is heated at the nip portion while being pinched and conveyed. In the image heating apparatus, the nip portion has a pre-nip portion formed by regions of the endless belts with no backup by pressure members, and a pressure nip portion where one endless belt with backup by the pressure members is held in contact with another endless belt. The image heating apparatus is capable of securing a large nip width compatible with an increase in speed and free from “pressure-absence” leading to image abnormality such as misregistration, thus enabling an image having a sufficient gloss to be obtained.
