    摘要: An image forming apparatus includes: an edge detection unit that detects one edge, in a conveyance direction, of a conveyed sheet; a passing detection unit that detects passing of the one edge; a judging unit that judges whether the edge detection unit or the passing detection unit has detected the one edge, within a predetermined monitoring time after the edge detection unit or the passing detection unit detected the one edge; a notifying unit that gives a notification indicating that front-back magnification correction is difficult to perform on the sheet when the judging unit has judged that the one edge is not detected within the monitoring time; an acquiring unit that acquires a desirable front-back magnification correction value input via an input unit according to the notification; and a correction unit that performs a front-back magnification correction process on the sheet, using the acquired front-back magnification correction value.

    摘要: A sheet length measuring apparatus includes first and second detection units respectively provided downstream and upstream of a conveyance unit, each detection unit detecting passage of an edge of a sheet medium; a first control unit to, until a predetermined set time passes since the detection of the passage of a leading edge of the sheet medium, regard detection of the passage of an edge of the sheet medium by each of the first and second detection units as not detected; and a second control unit to, when passage of an edge of the sheet medium is not detected again before a lapse of a predetermined monitoring time since the second detection unit detects passage of an edge of the sheet medium being passing a detection position of the second detection unit, judge that the edge detected by the second detection unit is a trailing edge of the sheet medium.
