发明名称 Sheet feeding device for an image forming apparatus
摘要 A sheet feeding device for an image forming apparatus of the present invention includes a sheet sustaining portion for sustaining a stack of sheets loaded on a bottom plate. Even when a great number of sheets are stacked on the bottom plate, the sustaining portion reduces a load to act on the bottom plate and thereby prevents the bottom plate and sheets from warping or sinking. This allows a pick-up roller to press the sheet stack with an adequate force and feed the sheets stably one by one.
