Patent number: 8746870Abstract: In a matting agent coating device, a matting agent within a supplying section is supplied to a metering section. A supplied amount of matting agent at a surface of a metering roller is metered by a metering blade, and an excess amount is filtered at a slit portion. Matting agent is supplied to an application roller that is provided directly beneath. For example, a closed-cell sponge rubber is used as a material of the metering roller, and a size of closed cells is around 5 to 100 times an average particle diameter of the matting agent. The matting agent that has been supplied to a surface of the application roller is transferred and applied onto a recording medium. The matting agent is transferred from the application roller onto image portions of the recording medium due to tackiness of an ink film forming an image.Type: GrantFiled: January 24, 2012Date of Patent: June 10, 2014Assignee: FUJIFILM CorporationInventors: Koji Furukawa, Kiyoshi Irita
