摘要： A sheet feeder includes an ejection tray, an ejector, an aligner, a pressing member, a friction member, and a switching device. The ejection tray stacks sheets. The ejector ejects a sheet to the ejection tray. The aligner is disposed downstream of the ejector in a direction of ejection of the sheet. The aligner is rotatable in a normal direction and a reverse direction. The pressing member applies pressure between the sheet and the aligner to enable the aligner to convey the sheet by rotation in the normal direction and the reverse direction. The friction member contacts the sheet ejected on the ejection tray to prevent conveyance of the sheet. The switching device switches contact and separation of the friction member with respect to the sheet.

摘要： A sheet feeding device includes a roller pair being mutually non-separable; and a roller pair being mutually separable. The sheet feeding device temporarily stops a sheet in a registration position of the non-separable roller pair and then resumes feeding the sheet. The sheet feeding device feeds sheets such that a following sheet reaches the registration position from the separable roller pair after completion of ejection of a preceding sheet.

摘要： A sheet feeding device feeds a sheet in a feed direction. The sheet feeding device includes a loading portion, a feeler, and a first detection sensor. The sheet is to be placed on the loading portion. The feeler rotates from a reference position to a pushed position around a support shaft in response to a push by a downstream end of the sheet, which is placed on the loading portion, in the feeding direction. The first detection sensor detects a rotation of the feeler from one of the reference position and the pushed position to the other of the reference position and the pushed position. The loading portion includes a second detection sensor to detect a state in which the sheet is placed on the loading portion.

摘要： A drive transmission device includes a plurality of drive transmission units and a heat-resistant member. The drive transmission units include a plurality of drive transmission mechanisms to transmit drive force from a plurality of drive sources to a driven member. At least two drive sources of the drive sources are included in at least two drive transmission units of the drive transmission units. The at least two drive sources are disposed at substantially a same height and on a same side with respect to at least two drive transmission mechanisms of the drive transmission mechanisms that correspond to the at least two drive sources. The heat-resistant member is disposed at a position higher than the at least two drive sources in a use state. The at least two drive transmission mechanisms are shielded from the at least two drive sources by the heat-resistant member at the position.
