摘要:
A loading device includes a disposing unit to dispose the recording media, and a detector to detect the disposed recording media. The disposing unit includes a loading member on which the recording media are loaded, a pair of guide members movable in width directions of the recording media that are mounted on the loading member, and a guide driver to move the guide members. The end detector detects positions at which the guide members are in contact with the recording media as the ends of the recording media. The guide driver further moves the guide members in the width direction to cause the recording media to form flexures, subsequently moves the guide members to separate from the recording media, and then moves the guide members to be in contact with the recording media again.

A print control unit causes a secondary-transfer control unit to move a secondary transfer unit apart from an intermediate transfer member, causes a direct-transfer control unit to cause a black image forming unit to form a black image and transfer the black image onto a transfer sheet being conveyed along a conveying path, and causes a positional-alignment control unit to perform positional alignment.
摘要:
A first alignment control unit causes a secondary transfer control unit to bring a transfer-sheet conveying belt and an intermediate transfer belt into contact with each other so as to transfer an alignment control pattern formed on the transfer-sheet conveying belt onto the intermediate transfer belt, whereby alignment for colors C and K is performed on the intermediate transfer belt, and furthermore a second alignment control unit causes the secondary transfer control unit to separate the transfer-sheet conveying belt and the intermediate transfer belt from each other so as to perform alignment for colors Y, M, and C, whereby alignment is performed for all the colors.

There are provided an image forming apparatus, an image forming method for the image forming apparatus, and a program that can reduce misalignment among images in all colors.Rotation of at least one of a transfer-sheet conveying belt 8 and an intermediate transfer belt 6 is controlled so as to match the phases of fluctuation of the surface speed of the intermediate transfer belt 6 and fluctuation of the surface speed of the transfer-sheet conveying belt 8, whereby it is possible to keep the periodical speed fluctuations of both the intermediate transfer belt 6 and the transfer-sheet conveying belt 8 to the minimum and reduce misalignment among images in all colors.

An image forming apparatus includes a first image forming unit that directly transfers an image onto a transfer sheet; an intermediate transfer member onto which an image is transferred; a secondary image forming unit that transfers an image onto the intermediate transfer member; a secondary transfer unit that transfers the image on the intermediate transfer member onto the transfer sheet; a fixing unit that fixes an image on the transfer sheet at a fixation position; and a guide member that guides the transfer sheet to the fixation position.

An image forming apparatus includes a direct-transfer control unit that causes a direct-transfer medium and a first image forming unit that forms a single-color image to transfer the single-color image onto either the direct-transfer medium or a transfer sheet; an indirect-transfer control unit that causes an intermediate transfer medium and a second image forming unit that forms a multi-color image to transfer the multi-color image onto the intermediate transfer medium; a secondary-transfer control unit that transfers the single-color image onto the intermediate transfer medium; a sensor that detects an image on the intermediate transfer medium; and a positional-alignment control unit that calculates, using the sensor, an amount of misalignment of the image and corrects, using a position of an image formed by the first image forming unit as a reference position, positions of images to be formed by the second image forming unit based on the calculated amount of misalignment.
