Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
74 words
An image fixing rotatable member comprising: a silicone rubber layer; a fluorine resin layer; and a primer layer for bonding said silicone rubber layer to said fluorine resin layer, wherein said primer layer includes a silane compound, a fluorine resin material in an amount grater than the silane compound and a binder material in an amount greater than said silane compound, said binder material comprising polyamideimide resin, polyimide resin, polyarylenesulfide resin, or silicone compound.
Claim 2
Dependent Claim
74 words
An image fixing rotatable member comprising: a silicone rubber layer; a fluorine resin layer; and a primer layer for bonding said silicone rubber layer to said fluorine resin layer, wherein said primer layer includes a silane compound, a fluorine resin material in an amount grater than the silane compound and a binder material in an amount greater than said silane compound, said binder material comprising polyamideimide resin, polyimide resin, polyarylenesulfide resin, or silicone compound.
Claim 3
Dependent Claim
