Abstract
Abstract An image fixing apparatus includes a heater which is fixed during an image fixing operation, a film for sliding movement of the heater, wherein a toner image on a recording material is heated by heat from the heater through the film, detecting means for detecting non-movement of the film, and power supply stopping means for stopping energization of the heater in response to an output of the detecting means.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
70 words
An image fixing apparatus, comprising: a heater which is fixed during an image fixing operation; a film for sliding movement relative to said heater; wherein a toner image on a recording material is heated by heat from said heater through said film; detecting means for detecting non-movement of said film; and power supply stopping means for stopping energization of said heater in response to an output of said detecting means.
Claim 2
Dependent Claim
70 words
An image fixing apparatus, comprising: a heater which is fixed during an image fixing operation; a film for sliding movement relative to said heater; wherein a toner image on a recording material is heated by heat from said heater through said film; detecting means for detecting non-movement of said film; and power supply stopping means for stopping energization of said heater in response to an output of said detecting means.
Claim 3
Dependent Claim
34 words
An apparatus according to Claim 1, further comprising a roll rotatable together with movement of said film, wherein said detecting means detects stoppage of said film by detecting stoppage of rotation of said roll.
Claim 4
Dependent Claim
27 words
An apparatus according to Claim 1, wherein said film is provided with a mark, wherein said detecting means detects the mark to detect stoppage of the film.
Claim 5
Dependent Claim
26 words
An apparatus according to Claim 1, wherein said heater includes a linear heat generating layer extending in a direction crossing a movement direction of said film.
Claim 6
Dependent Claim
80 words
An image fixing apparatus, comprising: a heater which is fixed during an fixing operation; a film for sliding movement relative to said heater; wherein a toner image on a recording material is heated by heat from said heater through said film; detecting means for detecting a film moving speed; and energization stopping means for stopping energization of said heater when said detecting means detects that the film moving speed detected by said detecting means becomes lower than a predetermined speed.
Claim 7
Dependent Claim
80 words
An image fixing apparatus, comprising: a heater which is fixed during an fixing operation; a film for sliding movement relative to said heater; wherein a toner image on a recording material is heated by heat from said heater through said film; detecting means for detecting a film moving speed; and energization stopping means for stopping energization of said heater when said detecting means detects that the film moving speed detected by said detecting means becomes lower than a predetermined speed.
Claim 8
Dependent Claim
36 words
An apparatus according to Claim 5, further comprising a roll rotatable together with movement of said film, wherein said detecting means detects the movement speed of said film by detecting a rotational speed of said roll.
Claim 9
Dependent Claim
26 words
An apparatus according to Claim 5, wherein said film is provided with a mark, wherein said detects movement speed of said film by detecting the mark.
