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.

Abstract: An image forming apparatus includes an image formation unit, an image heating unit, a placement unit, and a control unit. The image heating unit heats an image formed by image formation unit on the recording material that was placed on the placement unit. If an envelope is placed on the placement unit with a flap of the envelope in a direction perpendicular to a conveyance direction of a recording material, the control unit executed control to automatically execute two-sided printing on the envelope such that images formed on a first and a surface of the envelope are heated by the image heating unit. If an envelope is placed on the placement unit with a flap of the envelope in the conveyance direction of the recording material, the control unit executes control to inhibit execution of two-sided printing on the envelope.
