ENDLESS BELT DRIVING DEVICE AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an endless belt driving device capable of increasing a correction capability with a simple device configuration.SOLUTION: An endless belt driving device 70 includes: a belt driving part 71 having a rotating roller 73 and an endless belt 74; and a bias correction part 72 having a belt bias detection part 76 disposed apart from a side end 74a of the endless belt 74, and contacted and pressed by the side end 74a when the endless belt 74 is biased in the direction of a first rotation axis A1, and a belt pressing part 77 pressing the endless belt 74 so as to widen or extend a peripheral length of the endless belt 74 and imparting tension to an inner peripheral surface 74b of the endless belt 74. The belt bias detection part 76 and the belt pressing part 77 are rotatable around a second rotation axis A2. The belt pressing part 77 is connected to the belt bias detection part 76 via a rotation support part 78 formed on the second rotation axis A2.
