A sheet feeding apparatus comprising a feeding device for feeding a sheet, a regulating member for regulating a position of a lateral edge of the sheet fed by the feeding device, a first rotary member adapted to feed the sheet fed by the feeding device while urging the lateral edge of the sheet against the regulating member, a second rotary member adapted to feed the sheet fed by the first rotary member while urging the lateral edge of the sheet against the regulating member, and a guide device for guiding the sheet in such a manner that the sheet is curved between the feeding device and the first rotary member. An urging force of the first rotary member by which the sheet is urged against the regulating member is set to be equal to or smaller than an urging force of the second rotary member by which the sheet is urged against the regulating member.

An image recording apparatus for recording an image on a recording medium by using a transfer recording medium having a transfer recording layer whose transfer characteristics change on application of a plurality of kinds of energy thereto. The apparatus comprises: a conveyor for conveying the transfer recording medium; a recording section disposed along an advancing route of the transfer recording medium conveyed by the conveyor and having energy applicators for selectively applying the plurality of kinds of energy to the transfer recording medium; a transfer section for transferring an image formed on the transfer recording medium in the recording section onto the recording medium; and a contacting member disposed between the recording section and the transfer section in such a manner as to be brought into contact with the transfer recording medium. Members constituting the advancing route of the transfer recording medium are formed separably from a main body of the unit.
