Abstract: A sheet discriminator, which can be included in an image forming apparatus, includes an optical information detector, a sheet distinguisher, and a sheet thickness detector. The optical information detector includes a light emitter to emit light to a recording medium and a light receiver to receive the light and detects information of the recording medium. The sheet distinguisher distinguishes a type of the recording medium based on the information detected by the optical information detector. The sheet thickness detector includes a displacement gauge to sandwich the recording medium with an opposing member disposed facing the displacement gauge and to move from an initial position thereof and a displacement detector to detect an amount of displacement of the displacement gauge. The sheet thickness detector detects a thickness of the recording medium based on detection results obtained by the displacement detector.

Abstract: A sheet feeder, which is incorporated in an image forming apparatus, includes a sheet container, a sheet conveying member disposed facing a sheet stack that includes multiple sheet members loaded on the sheet container to separate an uppermost sheet member placed on the sheet stack from the other sheet members and to convey the uppermost sheet member, and a pressing member switchable between a pressing position to press the sheet stack from above and a retracted position to separate from the sheet stack.
