Image forming apparatus

An image forming apparatus including a gloss applying mode for applying gloss to an image formed with toner on a sheet and a non-gloss-applying mode for not applying gloss to the image on the sheet, the image forming apparatus comprising:

• a fixing device including a fixing member that is rotatable and a pressurizing member that is pressed into contact with the fixing member to form a fixing nip portion in which the toner is fixed to the sheet;
• a gloss applying device including a first rotating body including a heating unit and a second rotating body that is pressed into contact with the first rotating body to form a gloss applying nip portion in which gloss is applied to the fixed toner;
• and
• a conveying roller pair disposed within 210 mm from a back edge of the fixing nip portion to convey the sheet, wherein
• the fixing device, the gloss applying device, and the conveying roller pair are provided on a path line along which the sheet is conveyed, wherein
• when the sheet having a length that is less than 210 mm in a sheet conveying direction is conveyed in the non-gloss-applying mode, nip pressure of the gloss applying nip portion in the gloss applying device is less than that in the gloss applying mode, and
• when the sheet having a length that is greater than or equal to 210 mm in the sheet conveying direction is conveyed in the non-gloss-applying mode, the first rotating body and the second rotating body in the gloss applying device are separated from each other, and the sheet is conveyed by the conveying roller pair.
