摘要:
An image forming apparatus includes a printer and a controller. The printer transfers an image formed by attaching toner to an electrostatic latent image onto a sheet, heats and presses the sheet onto which the visible image is transferred to fix the image onto the sheet, and thereby forms an image on the sheet. The controller controls the printer to form an image for a second surface, and then to form an image for a first surface which differs from a surface on which the image for the second surface is formed, when the controller determines that duplex printing, in which decolorable toner is used on the first surface on which an image is first formed, and toner having a fixing temperature higher than a decolorizing temperature is used on the second surface, is set in printing job data.

An image forming apparatus including an image forming unit, a fixing unit, a temperature sensor, and a controller to execute a printing operation is provided. The printing operation is conducted at one of a first high-temperature printing pace, a first low-temperature printing pace, a second high-temperature printing pace, and a second low-temperature printing pace depending on a temperature detected by the temperature sensor. The first low-temperature printing pace is one of lower and equal to the first high-temperature printing pace. The second low-temperature printing pace is one of lower and equal to the second high-temperature printing pace. An absolute difference between the second high-temperature printing pace and the second low-temperature printing pace is greater than an absolute difference between the first high-temperature printing pace and the first low-temperature printing pace.

An image forming apparatus includes an image forming part to form a developer image on a recording medium, a fuser part that includes a fuser member and a heat application member to fix the developer image on the recording medium, a heat application control part to control the heat application member so that a temperature of the fuser member falls within a target temperature range that has been set, a temperature setting part to set a first target temperature range and a second target temperature range. The first target temperature range is a target temperature range for a first fusion that is performed on a first surface of the recording medium, and the second target temperature range is another target temperature range, which is lower than the first target temperature range, for a second fusion that is performed on the first surface of the recording medium.

摘要:
An approach is provided for reducing release agent transfer to a pressure member in a fuser. The approach involves causing, at least in part, at least a first sheeted substrate and a second sheeted substrate to be advanced through a fuser in a process direction. The approach also involves determining the presence of the first sheeted substrate at a fusing position. The approach further involves causing, at least in part, a fuser member and a pressure member to engage to form a fusing nip at the fusing position based, at least in part, on the determined presence of the first sheeted substrate at the fusing position. The approach additionally involves determining the first sheeted substrate has advanced through the fusing nip. The approach further involves causing, at least in part, the fuser member and the pressure member to disengage.

An approach is provided for applying a release agent to a substrate having at least a first surface and a second surface. The approach involves determining a print job type for applying one or more printed images to the substrate to be one of a simplex print job type that applies the one or more printed images to one of the first surface and the second surface and a duplex print job type that applies the one or more printed images to the first surface and the second surface. The approach also involves processing the determined print job type to cause, at least in part, a determination of a release agent application instruction that corresponds with the determined print job type. The approach further involves causing, at least in part, an amount of the release agent to be applied to the substrate based on the release agent application instruction.
