Abstract

A shape-correcting device, an electrophotographic device (incorporating the shape-correcting device), and a method therefor that correct shaping of a sheet, include a sheet guide member positioned in a sheet transport path upstream from an image forming module formed with an arcuate section that is convex relative to the surface of the sheet and a rotatable roller opposed to the arcuate section and slidable along a direction perpendicular to the rotation axis thereof. The roller rotates and presses the sheet against the arcuate section at a predetermined timing synchronized with a timing and position of the leading end of the sheet.
