Image forming apparatus

An image forming device includes: a conveyance unit; an image forming section; a plurality of storage units; and a sheet feeding roller, wherein provided are: one drive source; a first drive transmission system including a first one-way clutch; a second drive transmission system including: a second one-way clutch; and a first transmission interrupting unit; a third drive transmission system including: a third one-way clutch; and a second transmission interrupting unit; and a control unit, and the control unit is configured to: rotationally drive the drive source in the first direction at the time of the sending operation by the first sheet feeding roller; rotationally drive the drive source in the second direction at the time of the sending operation by the second sheet feeding roller; and rotationally drive the drive source in the second direction at the time of the sending operation by the third sheet feeding roller.

Image forming device

An image of the original document is read rapidly to effect quick production of the first copy even when the function of the shading correction and the function of the color/monochrome judgment operate. A waiting position P2 of a first slider 211 is located on the opposite side from a scan starting position P3 in reference to a reading area for the original document, and a location of a shading correction plate 206 is interposed between the reading area for the original document and the waiting position P2 of the first slider 211. While the first slider 211 is in the process of returning from the waiting position P2 to the scan starting position P3 for the preparation of reading the image of the original, a shading correction and a color/monochrome judgment are carried out for preventing the first slider 211 from having extra motion.
