Abstract
A sheet feed device includes: a sheet accommodation unit; a separation roller that applies conveyance force to sheets; and a separation resistance body including a friction portion facing the separation roller for separating the sheets one at a time. The sheet accommodation unit includes a guide portion provided at an upstream of the separation roller in a sheet feed direction for guiding the sheet. The separation resistance body includes an extension portion, which is pressed toward the separation roller while being supported to be contacted/separated to/from the separation roller, and which is extended upstream in the sheet feed direction from an upstream end portion of the separation resistance body. The guide portion and the extension portion are arranged in a line in a width direction. An upstream end portion of the extension portion is retreated with regard to a guide surface of the guide portion when feeding the sheets.
