摘要:
A fixer fixing a toner including a binder resin and a colorant on a recording medium upon application of at least one of heat and pressure, including: a fixing member fixing the toner on the recording medium; a pressurizing member pressurizing the toner thereon; and a cleaning member collecting the toner from the fixing member or the pressurizing member onto the cleaning member, wherein a storage modulus of the toner collected on the cleaning member is larger than a storage modulus thereof before fixed.
摘要:
A toner including a binder resin and a colorant which produces a torque of from 1.4 to 2.0 mNm, when a cone rotor having a vertical angle of 60° and grooves on a surface thereof intrudes into a bulk of the toner at an intrusion speed of 5 mm/min for a depth of 20 mm while rotating at a rotation speed of 1 rpm. The bulk of the toner is formed by consolidating 30 g of the toner in a cylindrical container having an internal diameter of 60 mm for 60 seconds with a consolidation load of 585 g.

摘要:
In a pressure-sensitive adhesive sheet 1 that comprises a base material 11 and a pressure-sensitive adhesive layer 12, and has formed therein by thermal processing a plurality of through holes 2 passing through one surface to the other surface of the pressure-sensitive adhesive sheet 1, as the base material 11, one is used for which, upon heating at a heating rate of 20° C./min under a nitrogen atmosphere, the temperature at a thermal decomposition peak where the mass reduction is greatest is not more than 450° C., or the difference between the temperature at the thermal decomposition peak and the temperature at a melting peak is not more than 250° C. According to this pressure-sensitive adhesive sheet 1, the appearance of the pressure-sensitive adhesive sheet 1 is not marred by the through holes 2 formed by the thermal processing.
摘要:
An image forming apparatus including an image bearing member; a charger; a light irradiator; a developing device; a transfer device; an imagebearingmember's cleaner; and a fixing device, wherein the fixing device includes a fixing member configured to fix a toner image upon application of heat and pressure thereto; a pressing member configured to press the recording material toward the fixing member; and a cleaning member configured to clean a surface of the fixing member and/or the pressing member, wherein the cleaning member has an outermost layer including a reactive material which increases viscoelasticity of a binder resin of the toner by reacting with the binder resin.
