Abstract
Official abstract text for this publication.
An endless belt for an image forming apparatus is provided with a resin layer having a sea-island structure including an island part containing a silicone-modified polyetherimide and a sea part containing a polyetherimide other than the silicone-modified polyetherimide and containing carbon black.
First claim
Opening claim text (preview).
What is claimed is: 1 . An endless belt for an image forming apparatus comprising: a resin layer having a sea-island structure including an island part containing a silicone-modified polyetherimide and a sea part containing a polyetherimide other than the silicone-modified polyetherimide and containing carbon black. 2 . The endless belt according to claim 1 , wherein the sea part contains a polyester. 3 . The endless belt according to claim 2 , wherein the polyester is at least one of polyalkylene naphthalate and a polyester elastomer. 4 . The endless belt according to claim 1 , wherein a melt flow rate of the polyetherimide other than the silicone-modified polyetherimide is equal to or greater than 15 g/10 min. 5 . The endless belt according to claim 2 , wherein a melt flow rate of the polyetherimide other than the silicone-modified polyetherimide is equal to or greater than 15 g/10 min. 6 . The endless belt according to claim 3 , wherein a melt flow rate of the polyetherimide other than the silicone-modified polyetherimide is equal to or greater than 15 g/10 min. 7 . A belt unit for an image forming apparatus comprising: the endless belt according to claim 1 ; and a plurality of rolls that support the endless belt in a state that tension is applied. 8 . An image forming apparatus comprising: an image holding member; a charging device that charges a surface of the image holding member; a latent image forming device that forms a latent image on the charged surface of the image holding member; a developing device that develops a latent image on the surface of the image holding member with a developer containing toner so as to form a toner image; an intermediate transfer belt that is the endless belt according to claim 1 ; a primary transfer device that performs primary transfer of the toner image formed on the surface of the image holding member to an outer circumferential surface of the intermediate transfer belt; and a secondary transfer device that performs secondary transfer of the toner image transferred to the outer circumferential surface of the intermediate transfer belt to a recording medium. 9 . A resin composition comprising: a sea-island structure including an island part containing a silicone-modified polyetherimide and a sea part containing a polyetherimide other than the silicone-modified polyetherimide and containing carbon black. 10 . A manufacturing method of an endless belt for an image forming apparatus comprising: forming a resin layer having a sea-island structure including an island part containing a silicone-modified polyetherimide and a sea part containing a polyetherimide other than the silicone-modified polyetherimide and containing carbon black. 11 . A manufacturing method of a resin composition comprising forming a sea-island structure including an island part containing a silicone-modified polyetherimide and a sea part containing a polyetherimide other than the silicone-modified polyetherimide and containing carbon black.
