Abstract: A cleaning blade includes a contact part coming into contact with a member to be cleaned, the contact part being configurated by a member containing polyurethane rubber produced by polymerizing at least a polyol component, which contains over 50 mol % and 75 mol % or less of 1,4-butanediol relative to the entire polyol components, with a polyisocyanate component. The ratio (M100/Re) of 100% modulus (M100 [MPa]) to rebound resilience coefficient (Re [%]) is 0.25 or more. The rebound resilience coefficient (Re [%]) is 25% or more.

Abstract: 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.

Abstract: A tubular member includes a siloxane-modified polyetherimide, a polyetherimide except the siloxane-modified polyetherimide, and a conductive material, wherein a content of the siloxane-modified polyetherimide with respect to a total content of the siloxane-modified polyetherimide and the polyetherimide except the siloxane-modified polyetherimide at a surface layer portion is 40% by weight or more.

Abstract: According to an aspect of the invention, a tubular member includes a siloxane-modified polyetherimide, a polyetherimide except the siloxane-modified polyetherimide, a polyether ether ketone, and a conductive material.

Abstract: A tubular body for an image forming apparatus is formed by subjecting a tubular member containing a thermoplastic resin to thermal processing. The thermal processing is performed so that at least one edge of the tubular member is thermally melted and then cured in at least a portion of the edge in a peripheral direction.

Abstract: Provided is a tubular body manufacturing method including preparing a resin composition containing a crystalline thermoplastic resin and molding the tubular body, using an extrusion molding machine that includes a cylindrical portion and a transport member which has a shaft member and a protrusion and is divided into a supply portion, a compressing portion and a measuring portion, by melting, kneading and transporting the resin composition through heating of the heat source and rotation of the transport member, and then extruding the molten resin composition, in which, when ?Tm (° C.) is a difference between a crystalline melt finish temperature and a crystalline melt start temperature of the crystalline thermoplastic resin, D (mm) is a diameter of the transport member, and Lc (mm) is a length of the compressing portion of the transport member, a relationship of following Expression (1) is satisfied: (?Tm/10)?3<Lc/D<(?Tm/10)+1.

Abstract: A shape adjusting mechanism for an extrusion molding machine includes a shape adjusting member, a blow-in mechanism, and a discharge mechanism. The shape adjusting member comes into contact with an inner circumferential surface of a molten substantially cylindrical resin extruded and transported from a ferrule provided to an extrusion molding machine, and adjusts the shape of the substantially cylindrical resin. The blow-in mechanism blows a gas into the substantially cylindrical resin transported between the ferrule and the shape adjusting member. The discharge mechanism discharges to the outside the gas in the substantially cylindrical resin transported between the ferrule and the shape adjusting member.
