A recording apparatus includes a conveyance unit, a conveyance path, a double-sided conveyance path, and first and second charge eliminators. The conveyance unit conveys a recording medium having first and second surfaces in a first direction through the conveyance path to a recording area where recording is performed by a recording unit on the first surface. The recording medium then passes through the double-sided conveyance path before recording is performed on the second surface. The first charge eliminator eliminates charges from the first surface and is disposed at a position downstream of a junction between the conveyance path and the double-sided conveyance path in the first direction and upstream of the recording area in the first direction. The second charge eliminator eliminate charges from the second surface and is disposed downstream of the junction in the first direction and upstream of the recording area in the first direction.

An image forming apparatus includes an engine to form an image on an image forming medium, a paper transfer device to pick up a printing paper and transfer the paper to a transfer path, a sensor to sense a printing paper at a predetermined position on the transfer path, and a processor to determine whether a transfer delay occurs, when the printing paper is sensed, and adjust a pickup timing to advance a pickup of a printing paper of a next page.

An image forming apparatus includes an image forming portion to form an image on an image bearing member, and a transfer portion to transfer the image on a first image position on the image bearing member to a sheet. In addition, a controller determines a second image position, on the image bearing member, of an image to be transferred onto a second surface of a sheet re-conveyed to an adjustment portion by a reverse and re-conveyance portion based on a detected side edge position, of a trailing part of the sheet being conveyed with a first end as the leading edge. The trailing part of the sheet is positioned on a trailing edge side further than a center position, in the sheet conveyance direction, of the sheet, and the controller determines a shift amount based on the second image position and detected side edge position of the sheet, which has been re-conveyed, being conveyed with the second end as the leading edge.

A fixing device includes: a heating section that heats in a non-contact manner a front surface of a recording medium; a feeding section that feeds the recording medium while causing the front surface to be opposed to the heating section; and a maintaining section that, in order to enable the recording medium to be fed by the feeding section while a rear surface that is opposite to the front surface, and that is in an image region where an unfixed-image is formed on the front surface is in a non-contact state, maintains the non-contact state.

An image formation apparatus includes: a transferrer that forms a toner image on an image formation surface of paper; a fixer that fixes the toner image on the paper; a paper conveyor that conveys the paper between an upstream side of the transferrer and a downstream side of the fixer in a paper conveyance direction; and a paper pre-heater that heats, on the upstream side of the transferrer in the paper conveyance direction, the image formation surface of the paper.

A static elimination device includes: a first static elimination member that makes contact with a medium that is transported; a second static elimination member arranged such that the medium is inserted between the first static elimination member and the second static elimination member; and a power source that applies a voltage to at least one of the first static elimination member or the second static elimination member, in which at least one of the first static elimination member and the second static elimination member has an elastic body.

A sheet conveyance apparatus includes a first conveyance portion configured to convey a sheet, a second conveyance portion configured to convey the sheet, the second conveyance portion including an abutment portion configured to form a loop on the sheet by being abutted against a leading edge of a sheet conveyed by the first conveyance portion, a curved guide portion, which is curved, configured to guide the sheet conveyed by the first conveyance portion to the second conveyance portion, and a rotary member arranged downstream of the first conveyance portion and upstream of the second conveyance portion in a sheet conveyance direction, and configured to be driven to rotate by a surface of the sheet that is guided by the curved guide portion, the surface sliding against the curved guide portion.

An image forming apparatus includes a controller to move a sheet, in an image formation process on a first surface, to a standard position in a width direction and move the sheet, in an image formation process on a second surface, in the width direction based on a detected position in a case where a difference between the standard position and a first position in the width direction is equal to or smaller than a predetermined value. The controller moves the sheet, in the image formation process on the first surface, by the predetermined value in the width direction and moves the sheet, in the image formation process on the second surface, in the width direction based on detected positions in a case where the difference between the standard position and the first position in the width direction is larger than the predetermined value.

An image forming apparatus includes an image forming device, a reading device, and processing circuitry. The image forming device forms a first image on a first face of a recording medium and form a second image on a second face of the recording medium. The first face and the second face are on opposite sides of the recording medium. The reading device detects a shape of the recording medium. The processing circuitry corrects the second image to be formed on the second face of the recording medium with respect to the first image formed on the first face of the recording medium based on the shape of the recording medium.
