An imaging system includes: a conveyor belt that conveys a medium having a toner image fixed thereto, along a conveying route; a heating element to heat the conveyor belt; and a pressing roller to press the conveyor belt against the heating element. The heating element may have a planar surface adjacent to an inner peripheral surface of the conveyor belt.

An image forming system includes an image forming unit, a varnish applying unit, a control unit that executes an operation in an image forming mode in which a toner image is formed on a recording material and a varnish image is formed on the recording material on which the toner image is formed, and an input unit that permits input of a line width adjusting value of either one of a line width of a portion of the varnish image overlapping with an image portion and a line width of a portion of the varnish image overlapping with a non-image portion, wherein the varnish image is formed so as to extend over an image portion where the toner image is formed on the recording material and a non-image portion where the toner image is not formed on the recording material.

An image forming system includes an image forming unit, a varnish coating unit, a reception unit, and a control unit. The image forming unit executes an image forming process of forming an image on types of recording media including a first type of recording medium with a coated layer and a second type of recording medium without a coated layer. The varnish coating unit executes a varnish coating process of varnish coating a recording medium on which an image is formed by the image forming unit. The reception unit receives a printing job from a user. The control unit controls the varnish coating unit. When the printing job received by the reception unit is a printing job for executing the varnish coating process on the second type of recording medium, the control unit controls the varnish coating unit to prevent the varnish coating unit from executing the varnish coating process.

An imaging system includes a toner transfer device, a leveling device and a glossing device. The toner transfer device transfers gloss toner to a surface of a medium. The leveling device levels a layer of the gloss toner on the surface of the medium. The glossing device performs a re-melting process and a cooling process on the medium after the layer of the gloss toner has been leveled.

An image forming apparatus includes a first image forming unit that develops a first latent image using a first developer so that a first developer image is developed with the first developer, a second image forming unit that develops a second latent image using a second developer, which is lower in saturation or higher in light-permeability in comparison to the first developer, so that a second developer image is developed with the second developer, a transfer part that transfers the first developer image and the second developer image to a medium, and a control part that controls an amount of the second developer used to develop the second developer image according to a type of the medium.

The glossing device performs a re-melting process and a cooling process on the medium after the layer of the gloss toner has been leveled.

Various variable gloss reduction techniques are disclosed. In one embodiment, a gloss reduction technique is disclosed using a textured roller and a wiper impregnated with fuser oil to create a differential gloss pattern that reduces the gloss of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a combination of heat and pressure to create a differential gloss pattern that reduces the gloss in specific regions of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a differential gloss pattern to generate a security mark on a printed image to prevent against copying or fraudulent misrepresentation of the image.
