Abstract: An image forming apparatus includes a gradation correcting portion, an image forming device, a toner image fixing device, a fixing device mounting portion, a detector, and an executing portion configured to execute a calibration process for generating a gradation correction condition on the basis of a result of detection of a predetermined toner image by the detector. The predetermined toner image is a toner image which is formed, on the basis of predetermined data, on the recording material by the image forming device and which is fixed by the fixing device mounted in the mounting portion, and the predetermined toner image forms a plurality of image regions different in density. The executing portion permits execution of the calibration process when the fixing device is the first fixing device, and prohibits the execution of the calibration process when the fixing device is the second fixing device.

Abstract: A fixing device includes a rotatable endless belt, a pressing roller and a fixing pad. The pressing roller contacts an outer peripheral surface of the belt and forms a nip portion in cooperation with the belt. A toner image is formed in the nip portion and fixed onto the recording material by application of heat and pressure. The fixing pad contacts an inner peripheral surface of the belt. The fixing pad includes a contact area in contact with the inner peripheral surface of the belt. The contact area includes a downstream end portion with respect to a conveyance direction of the recording material. The downstream end portion includes a central portion and both end portions with respect to a widthwise direction of the belt. The central portion locates downstream of the both end portions with respect to the conveyance direction.

Abstract: An image forming apparatus includes a rotary member, a web, a moving unit, a detecting unit configured to detect a predetermined position, and a control portion. The control portion informs, in a case where an actual moving amount per one winding operation is a first moving amount, the replacement of the web, if a number of sheets of recording materials on which images have been formed after the predetermined position is detected reaches a first number of sheets. The control portion informs, in a case where the actual moving amount per one winding operation is a second moving amount which is greater than the first moving amount, the replacement of the web, if a number of sheets of recording materials on which images have been formed after the predetermined position is detected reaches a second number of sheets which is less than the first number of sheets.
