The invention describes a sheet feed device having a sheet tray having a bottom plate defining a first portion of a storing portion that receives sheets therein, a feed roller, a separation plate, and a recessed portion formed in the separation surface. The feed roller moves to contact a sheet of the sheets, and to feed the sheet. The separation plate is disposed at a downstream end of the sheet tray and extends in a width direction. The separation plate has a separation surface which is inclined with respect to the bottom plate of the sheet tray, and defines at least a second portion of the storing portion. The recessed portion is formed in the separation surface and extends toward a downstream end of the separation surface. The separation plate is configured to separate the sheet from the sheets as the feed roller feeds the sheet.
