摘要： A kneaded material obtained by heating and melt-kneading a toner composition and a water-based medium containing water are put into a container of a granulating apparatus, and heated by a heater while agitating, to disperse the kneaded material into the water-based medium in its softened state. A temperature at which a loss tangent value of the kneaded material reaches a predetermined loss tangent value A, specifically, 0.5 or more and less than 5.0, is inputted to a granulating temperature input section as a setting granulating temperature T1. The heater is then controlled by a control section so that a granulating temperature as a temperature of the water-based medium measured by a thermometer reaches the setting granulating temperature T1 inputted to the input section. Accordingly, the granulating temperature as a temperature of the water-based medium, and thus a temperature of the kneaded material in the water-based medium is adjusted to T1.

摘要： Since the paper entry guide is disposed below and in close proximity to a fixing belt, the leading edge of recording paper can become wavy or curled when operated in a high temperature, high humidity environment or when printing on the reverse side of the paper in double-sided print mode, and this has lead to the problem that the leading edge of the recording paper after transfer is not properly inserted in the narrow spacing between the paper entry guide and the fixing belt, resulting in a recording paper jam. A fixing device comprises a fixing belt stretched around a heating roller with a heat source contained therein and a fixing roller, a pressing roller for pressing the fixing roller from below via the fixing belt, and a paper entry guide disposed below and in close proximity to the fixing belt and upstream of a nipping portion composed of the fixing belt and the pressing roller. The paper entry guide is pivotably supported on a fulcrum. A solenoid is provided at the upstream side of the paper entry guide, and a return spring is disposed above the paper entry guide. The solenoid, when in the ON state, pulls a plunger to its lowermost position against the spring force of the return spring, and thereby rotates the paper entry guide in the clockwise direction about the fulcrum to maintain spacing with respect to the fixing belt.

摘要翻译： 由于进纸导板设置在定影带的下方并且靠近定影带，所以当在高温，高湿度环境中操作时或当在双面纸张的背面打印时，记录纸的前缘可能变得波浪或卷曲 这导致如下问题：转印后的记录纸的前缘未被正确地插入纸入口引导件和定影带之间的窄间距中，导致记录纸卡纸。 一种定影装置包括：一个在其上容纳热源的加热辊周围拉伸的定影带和一个定影辊，一个用于经由定影带从下方按压定影辊的加压辊，以及布置在下方并且靠近 定影带和由定影带和加压辊构成的夹持部分的上游。 纸张进入指南可枢转地支撑在支点上。 在进纸引导件的上游侧设置有螺线管，在纸入口引导件的上方设有复位弹簧。 螺线管处于接通状态时，抵抗复位弹簧的弹簧力将柱塞拉至其最低位置，从而使进纸引导件沿支点的顺时针方向旋转，以保持相对于定影带的间隔。
