Abstract: An image forming apparatus has a photosensitive member, a charging member, an exposing device, a developing device, a transfer member, a polishing member, a driving device, a voltage applying device, a torque detector, and a control portion. The photosensitive member has a photosensitive layer and a surface protection layer formed on the surface of the photosensitive layer. The polishing member has an elastic layer on its circumferential surface, and rotates with a linear velocity difference from that of the photosensitive member. The torque detector detects the torque of the driving device. The control portion estimates an attachment condition of discharge products to the surface of the photosensitive member based on the torque of the driving device detected by the torque detector. When the torque is equal to or higher than a predetermined value, the control portion performs an image degradation suppression process.

Abstract: A fixing device includes a fixing belt, a pressuring member, a pressing member, a guiding member, a cap member, an elastic member and a detecting mechanism. The pressing member includes a pressing face pressing the fixing belt to a side of the pressuring member. The fixing belt includes a bulging part arranged at the downstream side from a fixing nip in a conveying direction. The cap member includes a facing part facing to the bulging part. Before the pressuring member comes into pressure contact with the fixing belt, a gap is arranged between the bulging part and facing part. When the pressuring member comes into pressure contact with the fixing belt, the bulging part bulges toward an external diameter side of the fixing belt to fill up the gap and the cap member is held by an end part of the fixing belt via the elastic member.

Abstract translation: 定影装置包括定影带，加压构件，按压构件，引导构件，帽构件，弹性构件和检测机构。 按压构件包括将定影带按压到加压构件的一侧的按压面。 定影带包括布置在沿着输送方向的定影辊隙的下游侧的凸出部。 盖构件包括面向凸出部的面对部。 在加压构件与定影带压力接触之前，在凸出部和面对部之间设置有间隙。 当加压构件与定影带压力接触时，凸出部分朝向定影带的外径侧凸起以填充间隙，并且帽构件通过弹性构件由定影带的端部保持。
