Abstract

A fixing device includes a fixing rotator to fix an image on a recording medium, a pressure rotator to press against an outer circumferential surface of the fixing rotator, a nip formation pad disposed inside the fixing rotator and opposite the pressure rotator to form an area of contact between the fixing rotator and the pressure rotator, and a slide member disposed between the fixing rotator and the nip formation pad and applied with lubricant to slide the fixing rotator in a sliding direction. The slide member includes first strands disposed parallel to the sliding direction and second strands disposed perpendicular to the sliding direction and interwoven with the first strands. The first strands are woven over the second strands longer than the second strands woven over the first strands.

First claim

What is claimed is:

1. A fixing device comprising:
a fixing rotator;
a pressure rotator to press against an outer circumferential surface of the fixing rotator;
a nip formation pad disposed inside the fixing rotator and opposite the pressure rotator to form an area of contact between the fixing rotator and the pressure rotator; and
a slide member disposed between the fixing rotator and the nip formation pad and applied with lubricant to slide the fixing rotator in a sliding direction,
the slide member including:
first strands disposed parallel to the sliding direction; and
second strands disposed perpendicular to the sliding direction and interwoven with the first strands,
the first strands being woven over the second strands longer than the second strands woven over the first strands, and
the first strands of the slide member are thicker than the second strands of the slide member.

2. The fixing device according to claim 1 , wherein there are fewer of the second strands of the slide member per unit area than the first strands of the slide member per unit area.

3. The fixing device according to claim 1 , wherein only the first strands of the slide member face the fixing rotator.

4. The fixing device according to claim 3 , the first strands of the slide member are woven alternately with respect to one second strand of the slide member.

5. An image forming apparatus comprising:
an image forming device to form a toner image; and
a fixing device to fix the toner image formed by the image forming device on a recording medium,
the fixing device including:
a fixing rotator;
a pressure rotator to press against an outer circumferential surface of the fixing rotator;
a nip formation pad disposed inside the fixing rotator and opposite the pressure rotator to form an area of contact between the fixing rotator and the pressure rotator; and
a slide member disposed between the fixing rotator and the nip formation pad and applied with lubricant to slide the fixing rotator in a sliding direction,
the slide member including:
first strands disposed parallel to the sliding direction; and
second strands disposed perpendicular to the sliding direction and interwoven with the first strands,
the first strands being woven over the second strands longer than the second strands woven over the first strands, and
the first strands of the slide member are thicker than the second strands of the slide member.

6. A sliding member applied with lubricant to slide a fixing rotator to fix an image on a recording medium, the sliding member comprising:
first strands disposed parallel to a sliding direction in which the fixing rotator slides on the slide member; and
second strands disposed perpendicular to the sliding direction and interwoven with the first strands,
the first strands being woven over the second strands longer than the second strands woven over the first strands, and
the first strands are thicker than the second strands.

7. The sliding member according to claim 6 , wherein there are fewer of the second strands per unit area than the first strands per unit area.
