摘要： An image forming apparatus includes: an image forming section; a pair of registration rollers; a displacement detection section; a displacement correction section; a translation amount determination section; and a control section configured to refer to a translation control table, operate the displacement correction section in accordance with a translation command value corresponding to a detection result obtained by the displacement detection section, obtain at a predetermined timing a relationship between the translation command value and a translation amount of the sheet, and update the translation control table on the basis of the relationship. The control section updates the translation control table when a displacement of a sheet is correctable, but does not update the translation control table when a displacement of a sheet is correctable.

摘要： An image forming apparatus includes: a transfer section that transfers an image onto a sheet; a sheet conveying member that conveys the sheet, the sheet conveying member being provided upstream of the transfer section in a sheet conveyance direction; and a hardware processor that controls displacement of the sheet conveying member so that the sheet is displaced along a width direction of the sheet. The hardware processor sets a displacement speed of the sheet conveying member for the sheet during transfer of the image by the transfer section to be lower than the displacement speed of the sheet conveying member for the sheet before the transfer of the image by the transfer section.

摘要： An image forming apparatus includes: a transferrer that transfers an image onto a sheet; a registration roller provided upstream of the transferrer in a sheet conveyance direction; and a hardware processor that controls an operation of the registration roller. The hardware processor executes a registration-less operation of not bringing a front end of the sheet in the conveyance direction into contact with the registration roller, and subsequently controls displacement of the registration roller so that a position of an image to be transferred onto the sheet by the transferrer can become correct according to sheet shape information representing a shape of the sheet.

摘要： An image forming apparatus includes an image former, a conveyance path, a flipping conveyance path, a conveying mechanism and a hardware processor. The flipping conveyance path includes a side path connecting a first branch point in a downstream of the conveyance path to a junction in an upstream of the conveyance path and a re-feeding path connecting a second branch point in the side path to a re-feeding point in an upstream of the conveyance path. The hardware processor controls the conveying mechanism to perform (i) a conveyance operation to convey the sheet along the conveyance path, (ii) a draw-in operation to draw the sheet with the image into the side path, and (iii) a re-feeding operation to convey the sheet in a reverse direction to re-feed the flipped sheet from the re-feeding point to the conveyance path.

摘要： An image forming apparatus includes a transfer unit, a sway roller pair constituted of a pair of rollers, a hardware processor and an image reader. The transfer unit transfers an image onto paper being conveyed to an image transfer position where the transfer unit transfers the image onto the paper. The sway roller pair conveys the paper to the transfer unit, the paper being conveyed to the sway roller pair. The hardware processor makes the sway roller pair sway based on predetermined sway control information. The image reader reads the paper onto which the image has been transferred by the paper having passed through the transfer unit. The hardware processor corrects the sway control information based on a reading result of the reading performed by the image reader.
