Abstract:
1. An image forming apparatus comprising: a transfer portion for transferring an image onto a sheet while feeding the sheet through a transfer nip; a fixing portion for fixing the image on the sheet while feeding the sheet, fed from said transfer portion, through a fixing nip; a sheet feeding guide, provided between said transfer portion and said fixing portion, having a guide surface for guiding the sheet; a sheet detecting portion, provided at a position between said transfer portion and said fixing portion, for detecting the sheet; and a controller for controlling a sheet feeding speed of at least one of said transfer portion and said fixing portion depending on an output of said sheet detecting portion so that a feeding attitude of the sheet fed while being sandwiched at both of the transfer nip and the fixing nip is maintained in a predetermined feeding attitude, wherein the guide surface of said sheet feeding guide has a most recessed region in a region between said transfer portion and said sheet detecting portion, wherein the guide surface in a position where said sheet detecting portion is provided with respect to a sheet feeding direction has a first region where said sheet detecting portion is provided and a second region spaced from said sheet detecting portion more than the first region with respect to a direction perpendicular to the sheet feeding direction, and wherein the first region is higher than the second region with respect to a direction perpendicular to the guide surface.
