Publication number: 20230398808Abstract: A pencil lead may achieve high levels of both improved density and improved fixability of a hand-drawn line and also be less likely to stain a hand during writing. Examples of this pencil lead include a pencil lead comprising a black porous fired lead body including at least graphite, wherein at least a compound selected from octyldodecyl erucate, oleyl oleate, octyldodecyl oleate, isopropyl palmitate, 2-ethylhexyl palmitate, and propylene glycol monooleate is impregnated in pores of the porous fired lead body. The pores of the black porous fired lead body are preferably impregnated with at least one selected from a terpene phenolic resin, a rosin ester resin, a ketone resin, and a rosin-modified phenolic resin, in addition to the compound.Type: ApplicationFiled: October 5, 2021Publication date: December 14, 2023Applicant: MITSUBISHI PENCIL COMPANY, LIMITEDInventors: Hiroyuki ARAI, Ryota KUBO, Masaaki MATSUMOTO

Patent number: 9482991Abstract: An image forming apparatus includes an image holding body, a developing device, a transfer device, a collection device, a container, and a transport member. The image holding body includes a surface on which a latent image is formed. The developing device develops the latent image into a visual image with developer. The transfer device transfers the visual image onto a transfer medium. The collection device collects the developer remaining on the surface of the image holding body after the visual image has been transferred. The container contains new developer supplied to the developing device. The image forming apparatus has a channel that has a first sub-channel and a second sub-channel. The developer flows into the first sub-channel from one of the collection device and the container and the second sub-channel from the other of the collection device and the container.Type: GrantFiled: May 20, 2015Date of Patent: November 1, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Ryota Kubo, Kiyotoshi Kaneyama, Kuniaki Tanaka, Yoshinobu Kariya, Hideaki Ozawa, Yasutomo Ishii, Yuki Sekura, Tatsuya Soga, Shintaro Hattori
