A hinge apparatus for a cover of an image forming apparatus has a hinge body with supporting brackets, movably inserted into a coupling hole positioned in a main body of the image forming apparatus, a hinge cam connected to the cover and pivotably connected to the supporting brackets, and a pressure device disposed at the hinge body to press the hinge cam. Accordingly, the hinge apparatus can be implemented with a simple and easy assembly operation, since it is not a complicated structural connection among the component parts of the hinge apparatus.

A sheet feeder includes a sheet placement unit to place a sheet, and an indicator indicating a predetermined position at which the sheet is to be set on the sheet placement unit. The indicator is movable between a first position at which the indicator is adjacent to or in contact with the sheet on the sheet placement unit and a second position farther than the first position from the sheet placement unit.

A fixing apparatus includes a heater including a heating member, a heater holder configured to hold the heater, a detection element configured to detect a temperature of the heater and disposed at a position that faces the heater in a third direction, a first holding member configured to hold the detection element, an urging member configured to urge the first holding member, a flexible member extending in the first direction and configured to support the first holding member on a first end portion of the flexible member in the first direction, and a second holding member configured to hold a second end portion of the flexible member in the first direction. The flexible member is flexible such that the first holding member and the second holding member are movable relative to each other in the third direction.

A printer includes a paper discharge tray that is configured to accumulate paper discharged from a discharge portion; and a holding member that is provided at a position where the paper discharged from the discharge portion is stacked, the holding member configured to be integrated with the paper discharge tray or held to be extractable from the paper discharge tray. The holding member includes a pair of side edge guide portions that are configured to guide opposite side edges of the paper. The holding member is configured to be held to be movable to a position of the paper in a width direction where the paper is stored between the pair of side edge guide portions in response to a force acting when the discharged paper comes into contact with the pair of side edge guide portions.

A document feeding device includes a sheet feed tray, a sheet discharge tray, and a restricting portion. The sheet feed tray feeds documents to be fed in a first direction. The sheet discharge tray, to which the fed document is discharged in a second direction opposite to the first direction, is arranged below the sheet feed tray. The restricting portion restricts movement in the second direction of the document discharged onto the sheet discharge tray. The restricting portion includes a first extension portion and a second extension portion. The first extension portion extends in the second direction from an end in the second direction of the sheet discharge tray. The second extension portion extends upward in an up direction from the first extension portion.

A conveying device includes a receptacle, an imager, and circuitry. The receptacle receives a medium. The imager captures an image of the medium. The circuitry acquires image information of the medium captured by the imager, and performs control based on at least one of a condition or a type of the medium. The at least one of the condition or the type is recognized based on the acquired image information.
