A driving apparatus for a double-side printable office machine includes a first driving part driving a pickup/transport unit, developing unit, and a second reverse-transport roller of a double-side printing unit, and a second driving part driving a fixing unit, a first reverse-transport roller of the double-side printing unit, and a paper discharge unit, and a controller controlling the first and second driving parts. A driving method in the double-side printable office machine includes stopping a first driving motor of the first driving part as a rear end of a sheet passes through the developing unit and reaches a certain position of a paper transport path, and driving the first driving motor of the first driving part in a paper transport direction again as the sheet enters the paper return path and reaches a certain position of the paper return path. Accordingly, the double-side printable office machine can reduce a size and a waste toner amount of the developing unit to decrease a manufacturing cost and reduce wear and tear and noise of the developing unit to enhance a lifespan and reliability of products by controlling paper pickup/supply and developing operations to be performed separately from an operation of fixing, discharging, and, in particular, returning sheets for double-side printings.
