Abstract
A fusing device thermally fuses a toner image formed on a sheet. The fusing device includes a sliding sheet having a sliding contact surface. The inner circumferential surface of a fusing belt comes into contact with and slides on the sliding contact surface. The sliding sheet has a fabric structure containing fluororesin fibers. The fluoroplastic fibers that are flattened by thermal pressure are disposed on the sliding contact surface, Thus, the sliding sheet has heat resistance.
Claims8
A sliding member having heat resistance, comprising:
- a fabric structure containing fluororesin fiber,
- the fluororesin fiber being flattened by thermal pressure and disposed on a sliding contact surface.
A fusing device that thermally fuses a toner image formed on a recording medium, comprising:
- a fusing rotary body;
- a heat source that heats the fusing rotary body;
- a pressurizing rotary body that comes into contact with an outer circumferential surface of the fusing rotary body to form a fusing nip between the fusing rotary body and the pressurizing rotary body, the pressurizing rotary body rotating the fusing rotary body;
- a sliding member having a sliding contact surface, an inner circumferential surface of the fusing rotary body coming into contact and sliding on the sliding contact surface;
- a fusing pad to which the sliding member is fixed;
- and
- a support member that supports the fusing pad,
- wherein the sliding member has a fabric structure containing fluororesin fiber, the fluororesin fiber flattened by thermal pressure is disposed on the sliding contact surface, and the sliding member has heat resistance.
