The image forming apparatus includes: a fixing unit for heating and fixing a toner image on a recording sheet (P); a secondary transferring portion for conveying the recording sheet (P) to the fixing unit; a loop sensor for detecting a degree of a loop of the recording sheet (P) generated according to a speed difference between a conveying speed of the fixing unit and a conveying speed of the secondary transferring portion; a CPU for controlling the conveying speed of the fixing unit; a fixing deliver sensor for detecting a used amount of the fixing unit; and an EEPROM for storing information on the used amount of the fixing unit detected by the fixing deliver sensor. The CPU controls the conveying speed of the fixing unit based on the information of the used amount of the fixing unit stored in the EEPROM and a detection result of the loop sensor.

摘要： A fixing apparatus includes a control circuit which controls the electrifying to a first heater so that a temperature detected by a first temperature detection portion reaches a first target temperature and controls the electrifying to a second heater so that a temperature detected by a second temperature detection portion reaches a second target temperature, when warm-up is initiated, and, when the warm-up initiated, if an initial temperature of a rotary member is below a predetermined temperature, the control circuit sets the first target temperature to a temperature value greater than the first target temperature set when the initial temperature of the rotary member is greater than the predetermined temperature and sets the second target temperature to a temperature value greater than the second target temperature set when the initial temperature of the rotary member is greater than the predetermined temperature. In this way, hot offset and poor fixing can be prevented and a pre-heating operation time can be prevented from extending excessively.

摘要： The image fixing apparatus forms a cleaning nip portion by pressing a web roll-up portion on a fixing rotation member with a feeding roller, a used portion for cleaning of the web is fed from a cleaning nip portion formation area, and during non-cleaning, a roller is at a waiting position at which the roller is farther from the fixing rotation member than its position during cleaning so as to separate the web roll-up portion from the fixing rotation member. Accordingly, it is possible to reduce degradation of a cleaning ability due to a toner component held by the used portion of the cleaning web.
摘要翻译：图像定影装置通过用进给辊将固定旋转构件上的卷筒纸卷起部分形成清洁夹持部分，用于清洁卷筒纸的使用部分从清洁辊隙部分形成区域进给，并且在非清洁期间辊子处于等待位置，在该等待位置，辊子比固定旋转部件在清洁过程中离开固定旋转部件的位置更远，从而将卷材卷绕部分与固定旋转部件分离。因此，可以降低由清洁纤维网的使用部分保持的调色剂成分引起的清洁能力的劣化。
