    摘要: The present invention provides an elastic body comprising addition reaction type silicone rubber elastic material obtained by curing polysiloxane mixture including at least (a) straight-chain dimethyl polysiloxane having the viscosity of 80000 poise or more at a temperature of 25°C and terminated with vinyl groups; and (b) resinous organopolysiloxane having at least two vinyl groups and having the viscosity of 10 poise at the temperature of 25°C and comprising a resin segment comprising at least one of a 4-functional constitutional unit and a 3-functional constitutional unit, and an oil segment comprising a 2-functional constitutional unit.
    The present invention also provides an elastic roller formed of such elastic body, and a fixing device having a fixing roller including an elastic layer formed of such elastic body.
