Abstract: A sheet post-processing device for post-processing of a recording sheet ejected from an image forming device in an ejection direction, the sheet post-processing device including: a first tray on which the recording sheet is placed after ejection; a push-out member that pushes out, in a push-out direction different from the ejection direction, the recording sheet placed on the first tray; and a guide member adjacent to an ejection direction downstream end of the first tray, the guide member supporting a portion of the recording sheet that protrudes from the first tray in the ejection direction. The guide member includes a resistive force reduction unit that reduces a resistive force that occurs due to contact between the guide member and the recording sheet, the resistive force hindering the pushing out of the recording sheet when the push-out member pushes out the recording sheet.

Abstract: A post-processing apparatus includes: a moving mechanism configured to move a punching apparatus in a width direction orthogonal to a transportation direction of a sheet; and a sensor configured to optically detect a mark formed on the sheet and indicating a position to be punched. The mark is configured such that an interval in the transportation direction between a plurality of feature portions extending in the width direction is configured to be changed depending on the width direction. The moving mechanism is configured to determine a position of the punching apparatus in the width direction based on a difference between respective timings of detection of the plurality of feature portions.

Abstract: An image forming apparatus including a polygon mirror that deflects a light beam includes: a light emitter that emits the light beam; an optical sensor that is disposed at a position on which the light beam deflected by the polygon mirror is incident; a detector that detects a minimum level being a light intensity level of the light beam, the lowest within a range detected by the optical sensor; a switcher that switches a light intensity level of the light beam emitted from the light emitter until the detector detects the minimum level; and a determiner that determines a degree of contamination of a component on an optical path of the light beam extending from the light emitter to the optical sensor, on the basis of the minimum level detected when the light intensity level is switched by the switcher.
