Abstract
An image heating apparatus for heating an image formed on a recording material includes a heating member, a backup member that cooperates with the heating member to form a nip for nipping and conveying the recording material, and a conveying member provided downstream of the nip in the traveling direction of the recording material. In such a construction, the conveying member is provided closer to the backup member than the heating member.
Claims6
An image heating apparatus for heating an image formed on a recording material, comprising:
- a heating member;
- a backup member that cooperates with said heating member to form a nip for nipping and conveying the recording material;
- and
- a conveying member provided downstream of the nip in the traveling direction of the recording material, wherein,
- in a case that the image is formed on one side of the recording material, said heating member faces the image,
- said heating member is arranged at an approximate same height or at a position lower than that of said backup member,
- said conveying member is provided closer to said backup member than said heating member,
- a peripheral speed of said conveying member is faster than that of said heating member, and
- a force by which said conveying member nips the recording material is smaller than a force by which said heating member and said backup member cooperate with each other to nip the recording material.
An image forming apparatus for forming an image on a recording material, comprising:
- fixing means having a nip for nipping and conveying the recording material, said fixing means including a heating member and a backup member that cooperates with the heating member to form the nip for nipping and conveying the recording material;
- and
- a conveying member provided downstream of the nip in a traveling direction of the recording material, wherein,
- in a case that the image is formed on one side of the recording material, said heating member faces the image,
- said heating member is arranged at an approximate same height or at a position lower than that of said backup member,
- said conveying member is provided closer to said backup member than said heating member,
- a peripheral speed of said conveying member is faster than that of said heating member, and
- a force by which said conveying member nips the recording material is smaller than a force by which said heating member and said backup member cooperate with each other to nip the recording material.
