An elastic body roller which has an excellent non-stick property or release property, and frictional force (gripping force) and is able to stably feed and guide a belt-shaped member such as a linerless label, a typical liner label, or the like is provided. Attention has been paid to coating an outer layer of an inner layer elastic material member having a silicone resin (a outer layer elastic material member) with a C hardness (hardness by a spring-type Asker C type defined in the SRIS 0101 standard) set low. An elastic material member of an elastic body roller has an inner layer elastic material member provided on the outer periphery of a roller shaft, and a outer layer elastic material member provided on the outer periphery of the inner layer elastic material member and being in contact with a belt-shaped member, and the outer layer elastic material member is formed from a silicone resin with a C hardness of 20 degrees or less.

A media sheet router moves sheets from a digital printer through the router and selectively to a plurality of finishers at full process speed. A router inlet path is aligned with the printer outlet path. Two router outlet paths are disposed at ninety degrees to the left and right of the router inlet path. The router outlet paths are each aligned with a finisher inlet path or another router. First and second turning elements are each mounted at forty-five degrees to the router inlet path and at ninety degrees to each other. Each turning element directs the sheets in a helical path to the router outlet paths. Transfer belts hold the sheets against each turning element. A bypass transfer moves the sheet to a bypass outlet path aligned with a bypass finisher inlet path. Diverters selectively direct the sheets onto the turning elements or the bypass transfer.

An image forming system includes an image forming apparatus including an image forming unit and a first control unit which controls the image forming unit, a varnish application apparatus provided downstream in a sheet conveyance direction with respect to the image forming apparatus and including a varnish application unit which applies varnish to a sheet and a second control unit which controls the varnish application unit, and a sheet conveyance apparatus provided between the image forming apparatus and the varnish application apparatus in the sheet conveyance direction and including a receiving roller which receives a sheet discharged from the image forming apparatus, a processing unit which performs predetermined processing on a sheet present in the sheet conveyance apparatus, and a third control unit which controls the processing unit, wherein the first control unit is capable of communicating with the second control unit and the third control unit.
