SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS

摘要

A sheet feeding apparatus includes a feed roller, a separation roller configured to form a separation nip portion with the feed roller, and a drive unit configured to drive the feed roller and the separation roller. A control portion to control the drive unit stops the drive unit with a sheet nipped at both the separation nip portion and a conveyance nip portion provided in a conveyance portion disposed downstream of the separation nip portion. In the case where a second sheet having lower basis weight than that of a first sheet is conveyed, the control portion set a stop timing of the drive unit to a timing later than that in the case where the first sheet is conveyed.

1. A sheet feeding apparatus comprising:
a feed roller configured to feed a sheet in a feeding direction; a drive unit configured to drive the feed roller; a separation roller connected to the drive unit through a torque limiter, the separation roller configured to be driven in a direction against the feeding direction so that sheets are separated at a separation nip portion formed between the feed roller and the separation roller; a conveyance portion configured to convey the sheet with a conveyance nip portion at which the sheet is nipped, the conveyance nip portion being disposed downstream of the separation nip portion in the feeding direction; and a control portion configured to execute a first control mode in which a first sheet is conveyed and a second control mode in which a second sheet having a lower basis weight than that of the first sheet is conveyed, the control portion starting the drive unit and stopping the drive unit with the sheet nipped at both nips of the separation nip portion and the conveyance nip portion in each of the first and second control modes, the control portion setting a stop timing of the drive unit in the first control mode to a timing later than that in the second control mode.
