    摘要： In a fixing apparatus using a fixing belt having an elastic layer as a fixing member and an image forming apparatus mounting such a fixing apparatus thereto, before a temperature detecting unit detects temperature change caused upon recording material conveying into a nip region, an electric power required to be applied to a heating element to heat the heating element is corrected to a predetermined electric power, and, when the fixing apparatus is started-up upon starting of print, at a predetermined timing, the electric power required to be applied to the heating element to heat the heating element is corrected to the predetermined electric power and a value of the predetermined electric power is substantially the same as an electric power value required for reaching the fixing apparatus to the predetermined power. The value of the predetermined power is determined in accordance with heat capacity of the recording material or a heat accumulating degree of the fixing apparatus on demand.

    摘要： A charge member charges secondary transfer remaining toner on an intermediate transfer member to a polarity opposite to a normal charge polarity. The remaining toner is moved by a transfer bias, from the intermediate transfer member onto an image bearing member. A BK station is arranged on the downstream of other stations. In a continuous BK monochromatic mode, by applying a reverse bias to transfer portions of the other stations and applying the transfer bias only to the BK station, remaining toner can be collected into the BK station (simultaneously with the transfer). In a full-color mode, remaining toner is collected into the station on the uppermost stream. Thus, the image bearing member for collecting remaining toner on the intermediate transfer member differs according to the mode, thereby suppressing the collection of remaining toner being concentrated on one image bearing member.

    摘要翻译： 充电构件将中间转印构件上的二次转印剩余调色剂充电到与正常电荷极性相反的极性。 剩余的调色剂通过转印偏压从中间转印部件移动到图像承载部件上。 其他车站下游设有BK车站。 在连续的BK单色模式中，通过施加反向偏压来转移其它工位的部分并将转印偏压施加到BK工位，剩余的调色剂可以被收集到BK工位（与转印同时）。 在全色模式下，剩余碳粉被收集到最上游的车站。 因此，根据模式，用于收集中间转印部件上的剩余调色剂的图像承载部件不同，从而抑制剩余调色剂的收集集中在一个图像承载部件上。

    摘要： An image forming apparatus includes an image forming station for forming a toner image on a sheet; an image heating portion including a flexible heating roller and a pressing roller to form a nip, the image heating portion being effective to heat while feeding the sheet, by the nip; a pressing state switching portion for switching a state of the nip between a pressing state and a released state; and a sheet feeding position detector for detecting misalignment of the sheet relative to a feeding reference position with respect to a direction perpendicular to a feeding direction of the sheet; wherein when the sheet feeding position detector detects the misalignment, the pressing state switching portion permits the nip to feed at least one sheet in a state of the misalignment, and then switches the nip to the released state and then switches to the pressing state.
