SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS

摘要

Provided are a sheet feeding device and an image forming apparatus which can feed a sheet by an electrostatic adsorption with a simple configuration and with low noises.;One end of a flexible adsorption member (29) is fixed to a holding member (24) rotating in a sheet feeding direction, and comes into surface contact with a sheet (P) stored in a sheet feeding cassette (20) while being elastically deformed when the holding member (24) is rotated, and adsorbs the sheet (P) by an adsorbing force by static electricity. Then, the sheet (P1) adsorbed to the adsorption member (29) is delivered to a registration roller (15) while winding up the adsorption member (29), and then the holding member (24) is stopped at a position where the adsorption member (29) is separated from the sheet.

主权项

1. A sheet feeding device comprising:
a loading portion configured to be loaded with a sheet; a rotation member configured to be disposed on an upper side of the loading portion; an adsorption member configured to have ends and to be provided such that a part of the adsorption member is fixed to the rotation member and the sheet loaded on the loading portion is electrically adsorbed; a driving unit configured to rotate the rotation member; and a control unit configured to control the driving unit.
