Abstract
Provided is a sheet feeding device and an image forming apparatus capable of performing sheet feeding by electrostatic adsorption at a low noise with a simple configuration. An adsorbing member 410 includes a straight line portion 410m and a curved portion 410n, and the adsorbing member 410 adsorbs a sheet through the curved portion 410n and conveys the sheet upward through the straight line portion 410m.
Claims11
A sheet feeding device, comprising:
- a loading unit that loads a sheet;
- a first rotating member that is arranged above the loading unit;
- an adsorbing member that includes a first portion and a second portion having a curvature larger than a curvature of the first portion and electrically adsorbs the sheet loaded on the loading unit, an inner side of the adsorbing member being supported by the first rotating member;
- a first nip member that nips the adsorbing member together with the first rotating member;
- a first driving unit that rotates the first rotating member and the first nip member;
- and
- a control unit that controls the driving unit,
- wherein the control unit adsorbs the sheet loaded on the loading unit through the second portion and then conveys the sheet upward through the first portion.
