ENDLESS BELT, ENDLESS BELT UNIT, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an endless belt that reduces the generation of cracks that are generated when the belt is stretched over a plurality of rolls including at least a roll having meander restriction guides at the ends while a tension is applied to the rolls and is driven to rotate repeatedly.;SOLUTION: An endless belt 101A for an image forming apparatus comprises a belt body part 103 that contains a resin A including a constitutional unit (a) having an imide bond; and an end reinforcement part 105A that is arranged at at least one end in a belt axial direction, at a position at which at least a surface on the center side in the belt axial direction is in contact with the belt body part 103, and contains a resin B including a constitutional unit (b) having an imide bond, the constitutional unit having a structure different from that of the constitutional unit included in the resin A, where the Young's modulus Y_B of an area including the end reinforcement part 105A in the belt axial direction is higher than the Young's modulus Y_A of an area not including the end reinforcement part 105A in the belt axial direction.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
