| 发明名称 | Fixing device and endless belt assembly | ||
| 摘要 | A fixing device includes an endless flexible belt, an elongated stationary pad, a rotary pressure member, a low-friction sheet of lubricant-impregnated material, a first adhesive layer, and a second adhesive layer. The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The elongated stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween. The low-friction sheet of lubricant-impregnated material covers the stationary pad to supply lubricant between the stationary pad and the belt across the nip. The first adhesive layer is disposed between the low-friction sheet and the stationary pad. The second adhesive layer is disposed between the low-friction sheet and the stationary pad. | ||

| 主权项 | 1. A fixing device comprising: an endless flexible belt looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof; an elongated stationary pad stationarily disposed inside the loop of the belt; a rotary pressure member disposed parallel to the belt, the rotary pressure member pressing against the stationary pad via the belt to form a nip therebetween, through which a recording medium is conveyed in a conveyance direction; a low-friction sheet of lubricant-impregnated material covering the stationary pad to supply lubricant between the stationary pad and the belt across the nip; a first adhesive layer disposed between the low-friction sheet and the stationary pad to bond the low-friction sheet to a first portion of the stationary pad at the nip; and a second adhesive layer disposed between the low-friction sheet and the stationary pad to bond the low-friction sheet to a second portion of the stationary pad which extends upstream relative to a center of the nip in the conveyance direction. | ||
