Patent number: 11427726Abstract: According to one embodiment, an ink which can be decolored upon heating is provided. Colored images can be formed with the ink by various methods, such as ink jetting or the like, then later the images can be decolored with heat. An ink according to an embodiment contains a color developable compound, a color developing agent that causes the color developable compound to develop a color, a nonaqueous solvent, and a decoloring agent that is insoluble in the nonaqueous solvent and decolors the color developable compound upon heating.Type: GrantFiled: August 20, 2019Date of Patent: August 30, 2022Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventors: Maiko Miyoshi, Tsuyoshi Itou, Takafumi Hara

Publication number: 20180356756Abstract: A fixing device includes a fixing member, a pressing member, and a slide-contacting member. The fixing member heats a sheet, on which a toner image is formed, while rotating. The pressing member comes into press-contact with the fixing member to form a nip section. The pressing member nips and transports the sheet while rotating along with the fixing member. The slide-contacting member is disposed to be in contact with the fixing member and performs slide-contact cleaning by urging a slide-contacting surface with respect to a surface of the rotating fixing member when a sheet on which a toner image containing a photoluminescent pigment is formed passes through the nip section.Type: ApplicationFiled: December 8, 2017Publication date: December 13, 2018Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA TEC KABUSHIKI KAISHAInventors: Taishi Takano, Maiko Miyoshi, Li Xu
