    摘要： A motion compensated prediction interframe coding system which includes a first checking portion for judging whether a motion compensation of a coding block is effective and outputting a motion compensation control signal representing the result of the judgement, a storage portion for storing motion vectors of the coding block and adjacent blocks and the motion compensation control signal, a second checking portion for comparing the motion vector of the coding block, of which the motion compensation should be effected, with each of the motion vectors of the adjacent blocks, of which the motion compensation should be effected, and judging that the intra-loop filtering processing to be performed after the motion compensation is ineffective if the number of the adjacent blocks, of which the motion vectors are identical with that of the coding block, is equal to or more than a predetermined number and that the filtering processing performed after the motion compensation is effective in another case, a motion-compensated brightness calculating portion for calculating motion-compensated brightness of pixels of the blocks, of which the motion compensation is effected, and a predictive brightness calculating portion for calculating predictive brightness of the pixels of the blocks by performing the filtering processing of the motion-compensated brightness of the pixels only if the filtering processing is effective. Thereby, the amount of the generated prediction error signals are reduced, and the picture quality is improved.

    摘要： An image forming apparatus includes an imaging unit, a fixing unit, a first thermometer, and a controller. The imaging unit forms a toner image on a recording medium conveyed along a media conveyance path. The fixing device is disposed downstream from the imaging unit along the media conveyance path to fix the toner image in place on the recording medium. The fixing device includes a fuser roller, a heat roller, an endless, fuser belt, and a pressure roller. The fuser roller has a cylindrical core of metal. The pressure roller presses against the fuser roller via the fuser belt to form a fixing nip therebetween. The first thermometer detects a first temperature at the cylindrical core of the fuser roller. The controller controls conveyance of the recording medium through the fixing nip according to the first temperature.

    摘要： A transfer fixing device includes a transfer fixing member, a pressure member, and a primary heater. The transfer fixing member defines a moving surface on which a toner image travels. The pressure member is pressed against the transfer fixing member to define a transfer fixing nip where the toner image traveling along the moving surface meets a surface of a recording medium traveling along the media conveyance path. The primary heater is located upstream of the transfer fixing nip along the media conveyance path to heat the surface of the recording medium before entering the transfer fixing nip. The heated surface of the recording medium fuses toner for transfer and fixing into place at the transfer fixing nip. The pressure member is at least partially electrically biased to generate an electrostatic field to promote transfer of toner at the transfer fixing nip.
