  • Publication number: 20240241468
    Abstract: An image forming apparatus includes an image forming unit, a heating rotary member, and a pressure rotary member that forms a nip portion with the heating rotary member to perform printing on a first recording material with a first width, a second recording material with a second width and has no image to be formed thereon, and a third recording material with the second width and has an image to be formed thereon. A time period from when the first recording material reaches the nip portion to when the second recording material that has no image to be formed thereon and follows the first recording material reaches the nip portion is shorter than a time period from when the first recording material reaches the nip portion to when the third recording material having an image to be formed thereon that follows the first recording material reaches the nip portion.
