IMAGE HEATING APPARATUS

摘要

An image heating apparatus includes a frame including a first side plate and a second side plate, a cylindrical rotatable member, a heater, a holder having a length longer than a distance between the first and second side plates, a first preventing member, and a second preventing member. An image formed on a recording material is heated by heat of the heater while moving in a state in which the recording material contacts the rotatable member. The holder is unintegral with the first and second preventing members. The holder includes a positioning portion, contacting the first side plate, for positioning a position of the holder with respect to the longitudinal direction.

1. An image heating apparatus comprising:
a frame including a first side plate provided at one end portion and a second side plate provided at the other end portion with respect to a longitudinal direction of said image heating apparatus; a cylindrical rotatable member provided between said first and second side plates; a heater contacting an inner surface of said rotatable member; a holder for holding said heater, wherein said holder is provided in an inside space of said rotatable member and with respect to the longitudinal direction, a length of said holder is longer than a distance between said first and second side plates; a first preventing member, contactable to one end surface of said rotatable member when said rotatable member moves toward said first side plate, for preventing movement of said rotatable member in the longitudinal direction; and a second preventing member, contactable to the other end surface of said rotatable member when said rotatable member moves toward said second side plate, for preventing the movement of said rotatable member in the longitudinal direction, wherein an image formed on a recording material is heated by heat of said heater while moving in a state in which the recording material contacts said rotatable member, wherein said holder is unintegral with said first and second preventing members, and wherein said holder includes a positioning portion, contacting said first side plate, for positioning a position of said holder with respect to the longitudinal direction.
