An information processing apparatus includes an acquisition unit, notification control unit, input unit, and extension unit. The acquisition unit acquires a measurement result obtained by measuring a printing medium characteristic and acquires a characteristic reference range of each of printing media types set in advance to identify a type of a measured printing medium. Extracting, as a candidate printing medium and based on the acquired measurement result and the acquired characteristic reference range, a type of printing medium using the characteristic reference range including the measurement result and notifying information indicating the type of the candidate printing medium are performed. The input unit inputs information, wherein a type of printing medium on which recording is to be performed by the recording unit has a first reference range which is the characteristic reference range of the type and corresponds to the input information. The extension unit extends the first reference range.

A sheet conveying device, which is included in an image reading device and an image forming apparatus, includes a passage forming body and a sound absorber. The passage forming body is configured to define a sheet conveying passage through which a sheet passes. The sound absorber includes a hollow portion and a communication portion configured to communication the hollow portion and the sheet conveying passage. A position of the communication portion of the sound absorber is changeable in the sheet conveying passage. The sheet conveying device included in the image reading device includes an original document conveying device configured to convey an original document having an image on a surface. The sheet conveying device included in the image forming apparatus includes a recording medium conveying device configured to convey the recording medium accommodated in a recording medium container to the image forming device.

A sheet conveying apparatus includes a sheet conveying member; a guide portion configured to define a sheet conveying path; a pressing portion configured to press the sheet to curve the sheet as viewed in a sheet conveying direction in the sheet conveying path; and a moving portion movable by an edge of the sheet passing through the sheet conveying path and arranged so that at least a part of a movable range of the moving portion is overlapped with the pressing portion. The moving portion includes a first abutment portion configured to abut against the sheet passing through the sheet conveying path on one side in the width direction with respect to a conveyance center of the sheet conveying member and a second abutment portion configured to abut against the sheet passing through the sheet conveying path on the other side with respect to the conveyance center.
