摘要： An image forming apparatus includes: a lubricant supply section that supplies a lubricant of a lubricant rod extending along an axial direction of an image bearing member onto the image bearing member; and a hardware processor that controls displacement of a sheet conveyance member so as to displace a sheet along a width direction of the sheet. The hardware processor performs control of changing a position in the axial direction of the toner image formed on the image bearing member on the basis of a distribution status of a toner in the axial direction in a toner image formed on the image bearing member, and controls displacement of the sheet conveyance member after a tip end of the sheet in the conveyance direction enters the transfer section so that a sheet position in a width direction of an image transferred onto the sheet is correct in the transfer section.

摘要： An image forming apparatus conveys a sheet to a transferring position of an image of a transferrer and transfers the image onto the sheet. The Apparatus includes a swing roller, a detector and a hardware processor. The swing roller includes a pair of rollers which conveys the conveyed sheet toward the transferrer. The detector is disposed in a second side path at a side facing an image side of the sheet to detect a position of a side end of the sheet and image information of the image transferred on the sheet. The second side path is provided to form an image on a back side of the sheet or to overlay an image on a front side of the sheet. The hardware processor swings the swing roller based on a detection result of the detector and predetermined swing control information.

摘要： An image forming apparatus includes a transfer section that transfers an image onto a sheet, a sheet conveying member that is provided upstream of the transfer section in a sheet conveyance direction and conveys the sheet, and a hardware processor that controls displacement of the sheet conveying member in such a way that the sheet is displaced along the width direction of the sheet. The hardware processor performs first displacement control in which the sheet conveying member is displaced in a direction which is specified in advance with respect to the sheet and in which an edge of the sheet in the width direction is directed toward a target position and second displacement control in which the sheet conveying member is displaced in the direction opposite the direction of the first displacement.

摘要： An image forming apparatus includes an image former, a fixing device, an image forming path, a circulation path and a hardware processor. Along the image forming path, paper is conveyed to the image former and the fixing device. The circulation path (i) diverges from the image forming path on a downstream side of the fixing device in a paper conveying direction and (ii) meets the image forming path on an upstream side of the image former in the paper conveying direction so as to circulate the paper such that an image forming side of the paper is unchanged. The hardware processor performs paper heating control to (i) make the paper pass through the fixing device without image forming on the paper, thereby heating the paper, and (ii) re-convey the paper via the circulation path to the image former.
