According to a sheet feeding method capable of successive image formation for use in an image formation apparatus with a sheet transport path for an upper sheet feeding cassette also serving as a portion of a sheet transport path for a lower sheet feeding cassette, the lower sheet feeding cassette initially starts feeding sheets. When the lower sheet feeding cassette runs out of sheets, a request is signaled to resupply sheets to the lower sheet feeding cassette and the upper sheet feeding cassette feeds sheets. When the lower sheet feeding cassette is resupplied with sheets, the lower sheet feeding cassette resumes feeding sheets.
