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.
