    Abstract: An image forming apparatus including a polygon mirror that deflects a light beam, the image forming apparatus includes: an optical sensor arranged such that the light beam deflected by the polygon mirror enters the optical sensor; and a hardware processor that measures an output level of the optical sensor and calculates, as a remaining life of the polygon mirror, an operation time of the polygon mirror to when the output level becomes a threshold value in a case of assuming that the output level ongoingly changes at a rate of change over time that is a change amount of the output level per unit operation time of the polygon mirror, using the measured output level.

    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.
