Abstract

A boundary is formed between a separating pad holding member and a separating pad in a sheet conveyance direction such that a sheet feeding device includes: a feeding roller having a feeding roller surface at a part in a rotational direction; the separating pad which separates the sheet at a holding portion between the feeding roller surface and the same; the separating pad holding member which presses the separating pad against the feeding roller; and a rolling member which is disposed coaxially with the feeding roller and abuts against the separating pad free from the holding state in cooperation with the roller surface; the feeding roller surface abutting against the separating pad holding member and the separating pad in this order, respectively, via the sheet S during the rotation of the feeding roller.

Description

technical field [0001] The present invention relates to a sheet feeding device that separates sheets such as originals or recording sheets one by one and feeds the sheets, and to an image forming apparatus such as a copying machine, facsimile machine, or printer having the sheet feeding device. Background technique [0002] In image forming apparatuses such as copiers or printers, for a sheet feeding device that separates sheets such as originals or recording sheets one by one and feeds the sheets, stabilization of feeding performance and reduction of operating noise have been required. There is a conventionally known sheet feeding device having a system of separating sheets one by one by a semicircular feeding roller and a separation pad pressed against the feeding roller. In the sheet feeding apparatus having this separation system, vibration may be generated between the feeding roller and the separation pad depending on the type of sheet to be fed, and furthermore, the vi...
