Abstract
The image heating apparatus comprises a heating member, a flexible sleeve, a guide member, a flange member, and a pressure member forming a nip part to nip and convey the heating member and the recording material through the sleeve. In this structure, in a recording material movement direction, a sliding-rubbing part of the flange member on a downstream side of the nip part has a shape to project the sleeve toward the downstream side, whereby an offset of image can be suppressed.
Claims5
An image heating apparatus for heating an image formed on a recording material, comprising:
- a heating member;
- a flexible sleeve for rotating around said heating member;
- a guide member, provided inside said sleeve, for guiding movement of said sleeve;
- flange members, provided at both ends of said guide member in its longitudinal direction, each having a part sliding and rubbing with an interior periphery surface of an end of said sleeve;
- and
- a pressure member for forming a nip part to nip and convey said heating member and the recording material through said sleeve,
- wherein, in a recording material movement direction, the sliding-rubbing part of said flange member on a downstream side of the nip part has a shape to project said sleeve toward the downstream side.
An image heating apparatus for heating an image formed on a recording material, comprising:
- a heating member;
- a flexible sleeve for rotating around said heating member;
- a guide member, provided inside said sleeve, for guiding movement of said sleeve;
- a pressure member for forming a nip part to nip and convey said heating member and the recording material through said sleeve,
- wherein, in a recording material movement direction, said guide member has a plurality of ribs on both an upstream side and a downstream side of the nip part, the number of ribs on the downstream side is smaller than the number of ribs on the upstream side, and the rib on the downstream side is larger than the rib on the upstream side.
