    摘要： A fixing device includes a primary heater disposed opposite a fixing rotator to heat a circumferential span of the fixing rotator other than a fixing nip formed between the fixing rotator and a pressure rotator and a secondary heater disposed outboard from the primary heater in an axial direction of the fixing rotator to heat the fixing rotator at the fixing nip. The primary heater and the secondary heater heat a bi-heating span of the fixing rotator in the axial direction thereof. The secondary heater heats a mono-heating span of the fixing rotator in the axial direction thereof and generates a decreased amount of heat to be conducted to the bi-heating span of the fixing rotator. The decreased amount of heat is smaller than an increased amount of heat to be conducted to the mono-heating span of the fixing rotator that is heated by the secondary heater only.

    摘要翻译： 定影装置包括与固定旋转体相对设置的主加热器，用于加热固定旋转器的周向跨度，而不是在固定旋转体和压力旋转体之间形成的定影辊隙和从主加热器的外侧沿轴向方向设置的二次加热器 固定旋转器用于在定影辊隙处加热定影旋转器。 主加热器和二次加热器沿固定转子的轴向加热固定转子的双加热跨度。 二次加热器沿固定旋转器的轴向加热固定旋转器的单加热跨度，并且产生传导到定影旋转器的双加热跨度的减少的热量。 减少的热量小于仅由二次加热器加热的定影转子的单加热跨度的加热量。

    摘要： A fixing device includes an endless belt, a heater disposed opposite the endless belt to heat the endless belt, and a pressing rotary body contacting an outer circumferential surface of the endless belt. A nip formation pad presses against the pressing rotary body via the endless belt to form a fixing nip between the endless belt and the pressing rotary body, through which a recording medium is conveyed. The nip formation pad includes a nip face disposed opposite the endless belt. The nip face includes a first region having an increased thermal conductivity and a second region having a decreased thermal conductivity and being adjacent to the first region in an axial direction of the endless belt.

    摘要： A fixing device includes: a rotatable fixing member formed as an endless belt; a heat source to heat the fixing member; a nip-forming member being not rotatable and arranged inside the fixing member; and a pressure member arranged outside the fixing member and forming a nip between the pressure member and the fixing member. The nip-forming member is formed of a first heat transmission unit and a sliding sheet. The first heat transmission unit includes an abutting part abutting the fixing member with the sliding sheet therebetween, and a bent part or bent parts extending inside the fixing member at upstream or upstream and downstream of the nip in a transport direction of a recording medium. A retaining part to catch and retain the sliding sheet is provided at a tip of at least the bent part at upstream of the nip in the transport direction.

    摘要： A fixing device fixes an unfixed image onto a recording medium by heating the recording medium conveyed to a fixing nip. The fixing device includes a rotator, a belt rotatable by contacting the rotator, and a fixing nip-forming member provided inside a loop of the fixing belt to together form the fixing nip with the rotator via the fixing belt. A sliding pad is placed between the fixing nip-forming member and the fixing belt to retain lubricant and render the fixing belt to smoothly slide thereon. The sliding pad includes a first fibrous layer contacting the fixing belt and a second fibrous layer closer to the fixing nip-forming member than the first fibrous layer. The second fibrous layer has less fiber density than the first fibrous layer.
