  • Publication number: 20240069839
    Abstract: An output system includes a terminal device, an image-forming apparatus, and a server device. The terminal device includes an acquirer that acquires content from the server device, a generator that generates job data including a setting for outputting the content based on the acquired content, a transmitter that transmits the job data to the image-forming apparatus, and a reception slip outputter that outputs a reception slip including a reception number corresponding to the generated job data. The image-forming apparatus includes a receiver that receives the job data from the terminal device, and an outputter that outputs the content after executing a job based on the job data corresponding to the reception number when the reception number is input.

    Abstract: Provided is a release control agent containing a silicone resin having a weight average molecular weight based on standard polystyrene by gel permeation chromatography of 3,000 to 6,000 and expressed by the average unit formula: (R13SiO1/2)a(SiO4/2)1.0, wherein each R1 independently represents an alkyl group with 1 to 6 carbon atoms, and “a” represents a number from 0.5 to 1.5, and (B) a diorganopolysiloxane having at least two silicon-bonded alkenyl groups in a molecule and/or (C) an ?-olefin with 12 to 24 carbon atoms. Also provided is a releasable film-forming silicone composition containing the release control agent. The releasable film-forming silicone composition forms a releasable film with little change in release force and that does not reduce the residual adhesive strength of a pressure sensitive adhesive (PSA) after long-term aging in a state adhered to the PSA despite exhibiting a relatively large release force with respect to the PSA.
