摘要： In a fixing device including (i) an external heat belt which abuts against a surface of a fixing roller so as to heat the fixing roller and (ii) a cleaning member which abuts against the external heat belt, a fixing temperature, which is a surface temperature of the fixing roller during a fixing process, is set per group into which recording media to be subjected to the fixing process are divided according to their widths in a direction of a rotary axis of the fixing roller, in such a way that the fixing temperature is set to a lower temperature for a group of narrower widths. This makes it possible to prevent a reduction in releasability of the fixing roller caused by a material, which is scraped off from the external heat belt by the cleaning member and then adhered to the fixing roller, thereby preventing the high-temperature offset.
摘要翻译：在一种定影装置中，包括（i）外部加热带，其邻接定影辊的表面以加热定影辊;以及（ii）与外部加热带抵接的清洁部件，定影温度是在定影处理期间定影辊的表面温度被设定为根据其在定影辊的旋转轴线的方向上的宽度被划分成待进行定影处理的记录介质的组，使得对于一组较窄的宽度，定影温度被设定为较低的温度。这使得可以防止定影辊由通过清洁部件从外部加热带刮掉并且然后粘附到定影辊上的材料引起的脱模性降低，从而防止高温偏移。

摘要： The image forming apparatus includes: an image forming portion having a multiple image forming stations each forming a color separated image; a transfer device for superimposing and transferring color separated images; a pattern image forming device for forming a predetermined pattern image; a pattern image density measuring device for measuring the density of the pattern image. In this configuration, the pattern image is formed so as to be greater than the measuring area of the pattern image density measuring device and is formed of multiple lines having a line width and a line spacing so that any part of the pattern image within the measuring area will produce an approximately constant measured density value. The image forming apparatus further includes a timing control device which performs control in such a sequence that one image forming station to be the reference, in the image forming portion, a pattern image; the image forming station to be adjusted forms another pattern image, which is superimposed over the pattern image formed by the reference image forming station; the pattern image density measuring device measures the density of the superimposed pattern image so as to judge the superimposed state of the pattern image based on the measured density; and the image forming station to be adjusted is controlled so as to perform image forming at a timing so that the measured density will fall within a predetermined permissible density range.

摘要： A belt conveyor member includes an endless belt and a cleaning blade. The cleaning blade is configured to remove residual toner remaining on a surface of the endless belt which is processed into a smooth surface. The endless belt has a first region and a second region. The first region is a region in contact with the cleaning blade which is located outside a region for a recording sheet of a maximum usable width to pass therethrough. The second region is located outside the first region. A contact surface between the cleaning blade and the first region is in a rough condition free from intimate contact.
