An image forming system includes an image forming unit including a first photosensitive member, a first developing unit, a second photosensitive member, a second developing unit, a third photosensitive member, a third developing unit, a fourth photosensitive member, and a fourth developing unit; a varnish applying unit; an irradiation unit; and a controller configured to control image formation by the image forming unit to form a black image, on which the varnish is superimposed, with yellow toner, magenta toner, and cyan toner.

Image forming system and image forming apparatus

An image forming system includes an image forming apparatus, a varnish applying apparatus, and a controller. A toner image formed on a recording material by the image forming apparatus on the basis of inputted first image data is a first toner image, and an image formed on the recording material by the varnish applying apparatus on the basis of inputted second image data is a varnish image. In a case that the varnish image is to be formed in a non-image region where the first toner image is not formed, before the varnish image is formed, a second toner image is formed with monochromatic toner by the image forming apparatus on a portion of the non-image region where the varnish image is to be formed.

Image forming system

An image forming system includes an image forming apparatus, a fixing device, a varnish image forming apparatus, an image reading portion, and a controller. The controller corrects first image data depending on first detection image data of a toner image formed on a first recording material and read by the image reading portion, and then depending on the corrected first image data, a toner image is formed on a second recording material subsequent to the first recording material. The controller corrects second image data depending on second detection image data of a varnish image read by the image reading portion, and then depending on the corrected second image data, a varnish image is formed on the second recording material.

Image forming system including varnish image forming apparatus

An image forming system includes an image forming apparatus, a varnish applying apparatus, an input unit, a first image processing unit, and a second image processing unit. The image forming apparatus forms a toner image on a recording material on the basis of image data obtained by subjecting first image data to data change processing. The varnish applying apparatus forms a varnish image on the recording material on the basis of image data obtained by subjecting second image data to the data change processing.

Image forming system including varnish applying apparatus

An image forming system includes an image forming unit, a varnish applying unit, a conveying unit, an irradiation unit, and a controller. The controller controls conveyance of a recording material so that a conveying speed of the recording material in a case that varnish is applied to the recording material with a toner image is formed is slower than a conveying speed of the recording material in a case that varnish is applied to the recording material with no toner image. The controller controls irradiation of the varnish with light so that intensity of the light with which the varnish is irradiated in a case that the varnish is applied to the recording material with the toner image is lower than intensity of the light with which the varnish is irradiated in a case that the varnish is applied to the recording material with no toner image.

A chord truss roof includes a ring-girder, cross beams arranged radially around the ring-girder, chord members stretched between the respective cross beams and the ring-girder. The roof supports itself by tensioning the chord members. The ring-girder has an upper compression ring, a lower tension ring, and plural struts connecting the two rings. The chord members arranged opposite one another with both end portions of the tension ring interposed therebetween are connected to the corresponding end portions of the tension ring, and are joined to one another via connection members which are disposed between both end portions of the tension ring. Further, each strut is provided along a line which bisects the angle made by a corresponding chord member and the plane defined by the tension ring.

Chord truss roof structure

With the conventional radiating truss roof support array, the inner-truss connecting members form multiple complete rings radiating from the central portion of the roof to the periphery at fixed intervals. When tension is applied to the periphery of the roof, a constricting annular compression is generated in each of the concentric rings of inner-truss connecting members. By this mechanism, the tension applied to the periphery is somewhat dissipated, and a less than optimal effect on the curvature of the dome of the roof is achieved for a given amount of tension applied to the periphery. The present invention concerns a radiating truss roof support array constructed in such a manner as to eliminate the above described problem of induced annular constriction in the concentric rings of inner-truss connecting members. This goal is achieved by interrupting the concentric rings of inner-truss connecting members at fixed intervals so that predetermined adjacent trusses are not connected together by the above mentioned inner-truss connecting members. the concentric rings of inner-truss connecting members thus formed are incomplete at predetermined portions and the annular constriction is thus eliminated. Thereby, the tension applied to the periphery of the structure is used to maximum effect in maintaining the curvature of the dome of the roof.
