Abstract
An image forming apparatus includes an image forming portion; a fixing device including a fixing member, a heating portion and a pressing member; a pressure switching mechanism configured to switch pressure between the fixing member and the pressing member; and a controller capable of executing an operation in an image forming mode in which the image is capable of being formed on the envelope by causing the pressure switching mechanism to switch the pressure to first pressure when an instruction to form the image on an address side of the envelope is inputted and by causing the pressure switching mechanism to switch the pressure to second pressure higher than the first pressure when an instruction to form the image on a non-address side of the envelope is inputted.
Claims14
An image forming apparatus capable of forming an image on a recording material including an envelope, said image forming apparatus comprising:
- an image forming portion configured to form a toner image on the envelope;
- a fixing device including a fixing member, a heating portion configured to heat said fixing member, and a pressing member contacting said fixing member and forming a nip where the envelope is nipped and fed, wherein said fixing device is configured to fix the toner image on the envelope by heat and pressure;
- a pressure switching mechanism configured to switch pressure between said fixing member and said pressing member;
- and
- a controller capable of executing an operation in an image forming mode in which the image is capable of being formed on the envelope by causing said pressure switching mechanism to switch the pressure to first pressure when an instruction to form the image on an address side of the envelope is inputted and by causing said pressure switching mechanism to switch the pressure to second pressure higher than the first pressure when an instruction to form the image on a non-address side of the envelope is inputted.
An image forming apparatus capable of forming an image on a recording material including an envelope, said image forming apparatus comprising:
- an image forming portion configured to form a toner image on the recording material;
- a display portion configured to display information;
- a stacking portion configured to stack the envelope fed to said image forming portion;
- a fixing device including a fixing member, a heating portion configured to heat said fixing member, and a pressing member contacting said fixing member and forming nip where the envelope is nipped and fed, wherein said fixing device is configured to fix the toner image on the recording material by heat and pressure;
- a pressure switching mechanism configured to switch pressure between said fixing member and said pressing member;
- and
- a controller capable of executing an operation in a double-side print mode in which images are automatically formed on both sides of an address side and a non-address side of the envelope,
- wherein said controller causes said display portion to display a stacking portion of the envelope stacked on said stack portion so that said pressure switching mechanism switches the pressure to first pressure when the image is formed on an address side of the envelope and so that said pressure switching mechanism switches the pressure to second pressure higher than the first pressure when the image is formed on a non-address side of the envelope.
