Patent ID: 8204405

Claim:
An image-forming device comprising: a main casing; a plurality of photosensitive drums that is accommodated in the main casing; a plurality of developing units that is disposed beneath the photosensitive drums and configured to supply toner to the photosensitive drums; a mounting member configured to detachably mount the developing units and configured to be pulled outward from the main casing; and a supporting member that has an upstream end portion in a pulling direction that the mounting member is configured to be pulled out from the main casing and being pivotably supported on the main casing about the upstream end portion, the mounting member being slidably supported on the supporting member in the pulling direction, the supporting member being configured to pivot with the mounting member between a first position where the developing units are configured to supply toner to the photosensitive drums and a second position where the developing units separate from the photosensitive drums, the mounting member being configured to be pulled out from the main casing if the support member is in the second position, wherein, when the supporting member is in the second position, a distance between the developing unit that is positioned at a most downstream side in the pulling direction and a corresponding photosensitive drum is greater than a distance between the developing unit that is positioned at a most upstream side in the pulling direction and its corresponding photosensitive drum.
