Title:
ENDLESS BELT DRIVE AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2002139112
Kind Code:
A
Abstract:
To provide an endless belt drive that stably operates without slippage and vibration belt such as a carrier belt and a transfer belt integrally even under an eccentricity of a rotor such as a photosensitive drum.
Roller pairs 62 are arranged in proximity to a drive roller 3 and a photosensitive drum 5 and in contact with a carrier belt 1. The eccentricities of the drive roller 3 and the proximate roller pair 62 are reduced to lessen fluctuations in speed of the carrier belt 1 while the drive roller 3 is controlled at a fixed angular velocity.
