摘要： A speed calculation device is provided. The generation component generates a plurality of pulse signals with different phases in accordance with rotation of a rotating body. The detection component detects rises and falls of respective pulses of the plurality of pulse signals generated by the generation component. The duration calculation component, each time a rise or fall is detected by the detection component, calculates a total duration of a pre-specified number of durations representing detection intervals of rises or falls detected prior to the rise or fall currently detected by the detection component. The speed calculation component calculates a speed relating to rotation of the rotating body on the basis of the total duration and a rotation angle of the rotating body that corresponds to one pulse of the pulse signals.

摘要： A registration pattern is formed on an intermediate transfer belt by using one photosensitive body. Pattern parts transferred onto the intermediate transfer belt vary in spacing due to speed variation occurring at the transfer time. The passing timing of the registration pattern is read through a read section placed downstream from the photosensitive body and speed (position) variation is sensed. The sense data is gotten over several cycles of the intermediate transfer belt and a low-frequency component caused by thickness unevenness of the intermediate transfer belt is extracted. The extracted data is subjected to the effects of variations at both the formation time and read time of the registration pattern and thus is corrected of calculating true speed (position) variation data. For example, a drive roll is controlled based on the data and an image is formed.

摘要： A roller mechanism includes a pair of rollers and an urging unit. The pair of rollers oppose one another sandwiching a conveyance path of a sheet material, and are provided to be capable of increasing and reducing an axis-to-axis separation thereof. The urging unit urges at least one of the pair of rollers in a direction of reducing the axis-to-axis separation of the pair of rollers with an urging force that increases with an increase in the axis-to-axis separation of the pair of rollers, and presses the sheet material with the pair of rollers. The urging unit increases the urging force non-linearly, with a rate of increase of the urging force falling as the axis-to-axis separation of the pair of rollers increases within a range of changes at times of sheet material-pressing.
