Abstract
In an image forming device of the present invention, which is a tandem type, electrophotographic image forming device, a first separating/contacting mechanism mechanically lowers/raises the whole of a transfer frame holding the transfer and transport belt unit in association with the opening/closing of a front door, a second separating/contacting mechanism mechanically lowers/raises the right side of the transfer frame in association with the opening/closing of a right side door, and a third separating/contacting mechanism mechanically lowers/raises the left side of the transfer frame in association with the opening/closing of a left side door. Therefore, the handling of a paper jam can be carried out even when power supply is cut off, and the transfer frame can be separated from the photoconductor drums just by opening a door from a plurality of access directions, on a side opened.
