A switching load distribution control unit 6 stores the output period information of each cell and designates a gate signal so that: in case of a pattern by which a cell is changed from ±1 level to 0 level, the cell having the longest ±1 level period information is set to 0 level; and in case of a pattern by which a cell is changed from 0 level to ±1 level, the cell having the longest 0 level output period is set to ±1 level. This distributes the switching load of each cell in the serial multiplex inverter control device.

Abstract: An image forming apparatus includes a first sheet path, a first sheet transfer mechanism, an ejection mechanism, a second sheet path, and a sheet flipping mechanism. The first sheet path is in a first side of the image forming apparatus. The first sheet transfer mechanism sends recording sheets from a sheet cassette through the first sheet path. The ejection mechanism switches between an ejection process and a duplex recording process. The second sheet path receives the recording sheet from the ejection mechanism and returns it to the image recording mechanism. The second sheet path is on the other side of the apparatus than the first side in which the first sheet path is arranged. The sheet flipping mechanism flips the recording sheet and has a flipping space in which the recording sheet is flipped without coming outside of the image forming apparatus. The ejection mechanism, the second sheet path, and the sheet flipping mechanism are located in a separate add-on unit.
