Publication number: 20150086919Abstract: A resin in a liquid developer contains 80 mass % or more of a urethane-modified polyester resin. A component derived from a polyester resin contains a constitutional unit derived from an acid component and a constitutional unit derived from an alcohol component. A ratio of a constitutional unit derived from an aliphatic monomer occupied in the constitutional unit derived from the acid component and the constitutional unit derived from the alcohol component is not lower than 90 mass %. Relation of |Tm1?Tm5|?20° C. (70° C.?Tm1?170° C., 60° C.?Tm5?120° C.) is satisfied, where Tm1 (° C.) represents a softening temperature T1/2 of toner particles measured with a flow tester under a load of 1 kg and Tm5 (° C.) represents a softening temperature T1/2 of toner particles measured with a flow tester under a load of 5 kg.Type: ApplicationFiled: September 17, 2014Publication date: March 26, 2015Applicant: Konica Minolta, Inc.Inventors: Naoki YOSHIE, Keiichiro HIGASHI

Patent number: 8822122Abstract: The present application discloses an image forming apparatus which uses at least two types of liquid developer to form a plurality of images that are superimposed on a sheet to form an image. The image forming apparatus includes a transfer mechanism configured to transfer the image to the sheet, an image forming mechanism configured to make the transfer mechanism carry the image, and a rubbing mechanism configured to rub the image on the sheet. The at least two types of liquid developer have different fixing properties from each other. The transfer mechanism includes a carrying surface configured to carry the image from the image forming mechanism. One of the plurality of images between the carrying surface and another of the plurality of images has higher fixing properties than the liquid developer used for forming the other image among the plurality of images.Type: GrantFiled: January 16, 2013Date of Patent: September 2, 2014Assignee: Kyocera Document Solutions Inc.Inventor: Tomohisa Soda
