Fixing device

A fixing device comprising:

• a tube;
• a heater extending inside an internal space of the tube;
• a nip plate extending inside the internal space of the tube;
• a backup member, the backup member and the nip plate configured to pinch the tube therebetween to define a nip region between the tube and the backup member, wherein a sheet is to be fed in a feeding direction at the nip region,
• a stay extending inside the internal space of the tube, the stay comprising:
• a first wall;
• a second wall disposed downstream relative to the first wall in the feeding direction;
• and
• a third wall connecting the first wall and the second wall;
• and
• a reflection plate extending inside the internal space of the tube, the reflection plate comprising:
• a central portion recessed toward the third wall of the stay, and
• a first extending portion extending upstream in the feeding direction from an upstream end of the central portion in the feeding direction,
• wherein the first extending portion of the reflection plate further extends to a position upstream relative to the first wall of the stay in the feeding direction, and
• wherein the first extending portion of the reflection plate further extends to a position upstream relative to an upstream edge of the nip plate in the feeding direction.

A fixing device comprising:

• a tube;
• a halogen lamp extending inside an internal space of the tube;
• a nip plate extending inside the internal space of the tube;
• a backup member, the backup member and the nip plate configured to pinch the tube therebetween to define a nip region between the tube and the backup member, wherein a sheet is to be fed in a feeding direction at the nip region,
• a stay extending inside the internal space of the tube;
• and
• a reflection plate extending inside the internal space of the tube, the reflection plate comprising:
• a reflection portion recessed toward the stay, and
• an extending portion extending in the feeding direction from a downstream end of the reflection portion in the feeding direction,
• wherein the stay has:
• a first wall, and
• a second wall disposed downstream relative to the first wall in the feeding direction,
• wherein the extending portion of the reflection plate further extends to a position downstream relative to the second wall of the stay in the feeding direction, and
• wherein the extending portion of the reflection plate further extends to a position downstream relative to a downstream edge of the nip plate in the feeding direction.
