Claims41
A pressure fixing method comprising
- passing a support carrying a toner image through a pair of rollers,
- said toner image consisting essentially of a toner which comprises
- a polybutadiene prepolymer having a number average molecular weight of up to 5000 and a polymer, wherein said polymer is admixed with, or polymerized in the presence of, said prepolymer, and said rollers are loaded with a linear pressure from 5 to 70 kg/cm, said prepolymer being present in an amount of from 1% to 40% by weight of said polymer.
A pressure fixing method comprising passing a support carrying a toner image through a pair of rollers, said toner image consisting essentially of a toner which comprises a polybutadiene glycol prepolymer, and said rollers being loaded with a linear pressure of from 5 to 70 kg/cm.
