Abstract

A multi-pass type image forming apparatus allows driving-couplings to couple with and separate from an image-carrier and developing units simultaneously. The apparatus includes a main body, a cover to open or close the main body, an image-carrier unit including an image-carrier and first driven-coupling connected to the image-carrier, developing units including a developing roller and a second driven-coupling connected to the developing roller, first and second driving-couplings to transmit drive power to the first and second driven-couplings, a link unit to move in a first direction in linkage with opening/closing operations of the cover, and a guide unit to be rotatable about the first driving-coupling in linkage with the link unit, the guide unit being moved when rotated about the first driving-coupling so as to couple or separate the first and second driving-couplings to or from the first and second driven-couplings.
