A roller-load changing apparatus usable with an office machine, such as a facsimile and a convergence machine, includes a document detecting sensor to determine whether a document is stacked, a feed roller to feed the document, a first pinch roller movable between a first pressing position to press the document against the feed roller and a first releasing position to release a pressing force of the first pinch roller, an ejection roller disposed in a downward document feeding direction of the feed roller to eject the document, a second pinch roller movable between a second pressing position to press the document against the ejection roller and a second releasing position to release a pressing force of the second pinch roller, and a roller-load changing unit to change the pressing position of the first and the second pinch rollers when a trailing portion of the document ejects from a nip formed between the feed roller and the first pinch roller
