Patent number: 9892350Abstract: An image-forming apparatus having an internal security paper detection unit and an image-forming method related to the apparatus. The image-forming apparatus controls a paper feed unit so as to feed a single sheet of paper from a paper stack unit when a command for forming an image on RF tag paper is input, controls a paper transfer unit so as to provide the paper fed from a security paper cassette unit to an image-forming unit along a transfer path, and controls the image-forming unit so as to normally form a desired image on the moving RF tag paper when an RF tag detection signal is input from an RF tag, paper detection unit, whereby the image is formed only on the security paper in which an RF tag is inserted and thus illegal leakage of documents may be prevented.Type: GrantFiled: April 26, 2016Date of Patent: February 13, 2018Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Min Sik Kim, Seung Jin Ryu, Han Jun Yoon, Do Hoon Lee, Nak Jun Jeong, Min Ho Noh
