Abstract

PURPOSE:To prevent the disorder of an image due to the dispersion of a toner reapprox.= sulting from triboelectric charging by bringing an antistatic roll into press contact with a fixing roll and earthing the core metal of the antistatic roll to eliminate triboelectric charging on the surface of the fixing roll. CONSTITUTION:The oil coating roll 4 of a roller fixing device provoded with a fixing roll 1 and a pressuring roll 2 is made of silicone rubber with low resistance such as <=106OMEGAcm volume resistivity, and the core metal 4a of the roll 4 is earthed 9. AC bias may be applied to the core metal 4a, and an antistatic roll may be set separately from the roll 4.
