Abstract: There is provided an aqueous heat-sealable resin composition which enables a laminate to have excellent heat sealing strength and blocking resistance. The disclosure relates to an aqueous heat-sealable resin composition which contains a urethane resin (A) which is a product of reaction components including a polyether polyol (a1), a polyisocyanate (a2) and a chain extender (a3) or the urethane resin (A) and a wax (B), and a laminate having a coating of the composition on at least one surface of a substrate.

Abstract: An image forming apparatus is provided. The image forming apparatus includes an image carrier, a conveyance belt which conveys a recording sheet via a position opposing the image carrier, a belt cleaner which removes adhered matters on the conveyance belt, a driving unit which drives the image carrier and the conveyance belt, a bias applying unit which applies a cleaning bias to the belt cleaner, and a controller which controls the driving unit and the bias applying unit such that when the image carrier is driven at a first speed, the cleaning bias is applied to the belt cleaner, and when the image carrier is driven at a second speed slower than the first speed, the cleaning bias is not applied to the belt cleaner.

Abstract: A microphase-separated structure comprising a block copolymer, which contains at least a block chain A consisting of a monomer A as a repeating unit and a block chain B consisting of a monomer B as a repeating unit, and a solvent, wherein the solvent has a temperature zone 1 where the block chain A and the block chain B are soluble and a temperature zone 2 where the block chain A is insoluble but the block chain B is soluble, and a structural period thereof varies by changing temperature between the temperature zone 1 and the temperature zone 2.
