Abstract
A sheet feeding device includes a sheet stacker, first and second feeders, a separation member, first and second sensors, and circuitry. The sheet stacker stacks multiple sheets including a sheet. The first and second feeder feed the sheet stacked on the sheet stacker in a sheet conveyance direction. The separation member contacts the second feeder to form a nip region. The first and second sensors detect the first or second sheet. The circuitry is to determine that a trailing end of the first sheet reaches at a given position downstream from the first sensor, and start feeding the second sheet in response to detecting the trading end of the first sheet by the second sensor, detecting the trailing end of the first sheet by the first sensor, or determining that the trailing end of the first sheet reaches at the given position.
