Problems solved by technology

In particular, when using paper other than plain paper, the conventional paper feeding device cannot properly feed the paper into the image forming unit due to the above two reasons
Therefore, it is possible to have side effects on the formed image due to the paper feeding failure of the paper feeding device.

Abstract

A recording-medium feeding device feeds a recording medium by separating loaded recording media sheet by sheet. An air outlet blows air to the recording media from a lateral side with respect to a direction of feeding the recording-medium. The air outlet is formed cross a recording-medium feeding plane, such that an upper edge in an upstream of the recording-medium feeding direction is higher than an upper edge in a downstream of the recording-medium feeding direction.

Description

technical field [0001] The present invention relates to a recording medium feeding device for an image forming apparatus such as a copier, a printer, or a facsimile to facilitate feeding of a recording medium. Background technique [0002] Conventionally, a paper feeding device known from image forming apparatuses such as copiers and printers is to separate the paper sheets one by one by blowing air from an exhaust port to the paper sheet, thereby transferring the paper sheets from the loaded A bundle of paper in the loading unit is fed to the imaging element or printing element. In particular, there is known a structure in which nozzle openings are provided on a part of the side rails below the passage of paper fed from a paper tray, and a pair of such nozzle openings are uniformly arranged on a pair of side rails disposed opposite to each other. above (see, for example, Japanese Patent Application Publication No.: 2007-008656). [0003] Another known paper feeding device...
