摘要： 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.

摘要： An image forming apparatus includes a sheet feed unit having a sheet feed port, an image forming unit, a sheet position detector, a mode selector, and a memory unit. The sheet feed unit feeds a recording sheet. The image forming unit forms an image on the recording sheet. The sheet position detector detects a sheet edge of the recording sheet. The mode selector selects at least one of the position correction mode and non-correction mode for the sheet feed port. An image forming position on the recording sheet is corrected using position information detected by the sheet position detector when the position correction mode is selected, and the image forming position on the recording sheet is not corrected when the non-correction mode is selected. A memory unit may store a plurality of values of light intensity and threshold value corresponding to different types of recording sheets.
