SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS

摘要

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 400 is arranged to be rotatable in synchronization with rotation of one driving roller (rotary member) 401, and while the driving roller 401 is performing one rotation, the adsorbing member 400 adsorbs and feeds a sheet from a standby position, and then the adsorbing member 400 returns to the standby position again.

主权项

1. A sheet feeding device, comprising:
a loading unit that loads a sheet; a rotary member arranged above the loading unit; an adsorbing member that is arranged to be movable in synchronization with rotation of the rotary member and electrically adsorbs the sheet loaded on the loading unit; a driving unit that rotates the rotary member; and a control unit that controls the driving unit, wherein the control unit causes the sheet loaded on the loading unit to be adsorbed on the adsorbing member by increasing a downward looseness amount of the adsorbing member, and then feeds the sheet adsorbed on the adsorbing member while reducing the downward looseness amount of the adsorbing member, and the control unit performs one rotation of the rotary member to move the adsorbing member from a standby position, causes the sheet to be adsorbed and fed, and then moves the adsorbing member to the standby position.
