Abstract
An intermediate transfer belt has a first region and a second region in an outer circumferential surface thereof that is in contact with a blade. The first region has a first dynamic friction coefficient in a belt conveyance direction, and the second region has a second dynamic friction coefficient. The distance of the second region in the belt conveyance direction is less than the distance of the first region and is greater than the distance of a contact portion in which the blade is in contact with the intermediate transfer belt.
Claims5
A movable endless intermediate transfer member, that is moveable in a movement direction when used in an image forming apparatus, for transferring a toner image from an image bearing member, comprising:
- a plurality of grooves, formed on an outer circumference surface thereof, and continuously extending in a direction along the movement direction of the intermediate transfer member, the grooves being arranged in a width direction crossing the movement direction of the intermediate transfer member, and
- wherein the grooves are diagonally formed at an angle θ to the movement direction and satisfies the following Expression (1):
- I≤L×tan θ
- where I represents an interval between adjacent ones of the grooves in the width direction, and L represents a circumferential length of the intermediate transfer member in the movement direction.
