摘要： An image compression unit includes a block divider that divides image data into a plurality of blocks, a DCT portion that subjects the image data of each block to DCT, a quantization factor output portion that outputs a quantization factor as a numerical value indicative of fineness of quantization, a correction value computation portion that computes a correction value that is determined uniquely according to a position of a block of image data, a quantizer that quantizes the data having been subjected to DCT, based on a value obtained by multiplying the correction value by the quantization factor, and an encoder that encodes the quantized data and outputs compressed data. This configuration makes it possible to provide an image compression/decompression unit that is capable of varying a compression ratio in a frame, without encoding compression parameters of each block.

摘要： A fixing device switches ON a heater lamp of the press roller in a fixing device in a color print mode. In a monochromatic mode, power comparable to the power consumption of the heater lamp can be supplied additionally to an exciting coil on the heat roller side when a heater lamp 3 stays OFF. An amount needed for the heat roller can be therefore added flexibly to the exciting coil. During a warm-up, power comparable to power consumption of the option can be supplied additionally to the exciting coil on the heat roller side.

摘要： A fixing apparatus of an embodiment of the invention includes an auxiliary pressure member to press a belt to a heat roller side. A belt mechanism to integrally support the belt and the auxiliary pressure member is rotated so that the belt is spaced from the heat roller except for a necessary time. The temperature gradient characteristic of the surface temperature of the heat roller is compared with a reference temperature gradient characteristic, and a correction value of power supplied to a coil is estimated. The correction value is added to the supply power obtained from the detection result of a sensor, and control power for controlling an inverter drive circuit is obtained.

摘要： A heat fixing member according to the invention has a surface layer formed on the surface of the substrate with a three-layer structure of a primer layer, an middle layer, and a topcoat layer. The binder-resin content decreases in order from the primer layer to the topcoat layer. The fluorocarbon-resin content increases in order from the primer layer to the topcoat layer. The topcoat layer is made of a fluorocarbon resin having high ability of release and a fluorocarbon resin having high abrasion resistance. Thus, the surface layer can be prevented from peeling without losing ability of release and can be decreased in abrasion.

摘要： A printer comprises a removable process unit which includes a photoconductive drum and an image forming section for forming an image on the drum. The process unit is provided with a removing member for removing dust from a transfer medium adhering to an aligning roller and a dust storage section for storing the dust removed by the removing member. The storage capacity of the dust storage section is larger than a capacity equivalent to the volume of the dust removed as the transfer medium corresponding in quantity to the service life of the process unit is processed.
