An image forming apparatus includes an image forming unit that forms an image on a recording medium, a reversal transport unit that reverses front and back sides of the recording medium having an image formed by the image forming unit, and then transports the recording medium to the image forming unit, a detection unit disposed in a transport path of the reversal transport unit to detect the position of the recording medium in a transverse direction transverse to a transport direction, the transport direction being the direction of transport of the recording medium, and an adjustment unit that adjusts the position of an image in the image forming unit in accordance with the position of the recording medium detected by the detection unit.

An image forming apparatus employing an electrophotographic image forming unit and an inkjet image forming unit, thereby being capable of printing an image on each of a front surface and the back surface of a recording medium,

An image forming apparatus sets, in a case where a mode for executing a heating process a plurality of times is set, a target temperature of a fixing unit during a second heating process depending on image information about a toner image to be formed on a first surface of a recording medium immediately before a first heating process.

An image forming apparatus includes an image forming unit, a fixing unit including a first rotary member and a second rotary member, a reciprocation mechanism configured to reciprocally move the fixing unit in a width direction, a duplex conveyance unit configured to reverse a recording material of which a toner image is fixed on a first surface and reconvey the recording material to the image forming unit in a double-sided image formation in which toner images are formed and fixed on the first surface and second surfaces of the recording material, and a control unit configured to control the reciprocation mechanism not to move the fixing unit in the width direction while the fixing unit is nipping and conveying the recording material at a fixing nip portion for fixing the toner image on the first surface of the recording material in the double-sided image formation.

An image forming apparatus includes a conveying device, an image forming device, a reading device, and control circuitry. The conveying device sequentially conveys a plurality of successive recording media that includes a preceding recording medium and a following recording medium. The image forming device forms an image on each of a front surface and a back surface of the preceding recording medium conveyed. The reading device reads an outer shape of the preceding recording medium. The control circuitry calculates an amount of deformation of the preceding recording medium based on the outer shape of the preceding recording medium read. The control circuitry corrects at least one of a front image and a back image based on the amount of deformation calculated, to cause the image forming device to form the front image and the back image on a front surface and a back surface, respectively, of the following recording medium.

An image forming apparatus employing an electrophotographic image forming unit and an inkjet image forming unit, thereby being capable of printing an image on each of a front surface and the back surface of a recording medium.

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 according to one embodiment includes a transport unit, an image forming unit, a heating member, a first pressurizing member, a second pressurizing member, and a processor. The transport unit is configured to transport a print medium. The image forming unit is configured to form a toner image on the print medium by a first toner. The first pressurizing member is configured to form a fixing nip for fixing with the heating member. The second pressurizing member is configured to form a decolorizing nip for decolorizing with the heating member. The processor is configured to control the heating member to the first temperature, allows the print medium on which the toner image is formed by the first toner to pass through the fixing nip, and allows the print medium on which an image is formed by a second toner, to pass through the decolorizing nip.

A method for fluid-density modulated auto-duplexing is disclosed. This method determines when a final swath of a printing operation on a surface of a media occurs within a predefined distal end portion of the media. An estimated media dry time after the final swath in the predefined distal end portion is determined to be greater than a predetermined time. The estimated dry time is capped to a predetermined minimum media dry time and a course of action for a feed mechanism is selected to reduce curling and cockling of the media. Furthermore, a non-transitory computer readable medium and a printer having fluid-density modulated auto-duplexing are also disclosed.

An image forming apparatus includes an image forming device; a fixing device; a first conveyance passage downstream from the fixing device in a sheet conveyance direction; a second conveyance passage downstream from the fixing device and communicating with the first conveyance passage; a sheet reversing member to reverse a conveyance direction of the sheet to the second conveyance passage; a divider to switch a route of the sheet between the first conveyance passage and the second conveyance passage; and a sheet detection sensor disposed downstream from the fixing device and upstream from the divider. The first conveyance passage includes a sheet outlet from which the sheet is ejected outside the apparatus. The apparatus further includes a ventilation passage communicating with an outside, to guide air from the outside to pass the sheet detection sensor and enter at least one of the first conveyance passage and the second conveyance passage.
