an urging portion configured to urge said first container and said second container toward each other to (i) close said first opening by said second container and (ii) close said second opening by said first container.
3. A gloss processing apparatus for glossing at least part of a toner image formed on a sheet, said apparatus comprising:
(i) a main body of said apparatus including a movable portion;
(ii) a film cartridge detachably mountable to said main body, said film cartridge including
(ii-i) a film;
(ii-ii) a first roller configured so that said film can be wound thereon;
(ii-iii) a first container configured to contain said first roller, said first container having a first opening configured to permit passage of said film therethrough;
(ii-iv) a second roller configured to wind up said film;
(ii-v) a second container configured to contain said second roller, said second container having a second opening configured to permit passage of said film therethrough; and
(ii-vi) an abutting portion configured to abut said movable portion with a moving operation to receive a force for causing said first container and said second container to move away from each other.
4. A gloss processing apparatus according to claim 3 , wherein said movable portion includes a heater, including a plurality of heating elements arranged along a direction substantially perpendicular to a sheet conveying direction, configured to heat the toner image on the sheet through said film, and wherein said heater contacts said film with movement of said first container and said second container away from each other.
5. A gloss processing apparatus according to claim 4 , wherein said main body includes a pressing roller configured to press said film toward said heater.
6. A gloss processing apparatus according to claim 3 , wherein said main body includes a closing mechanism configured to (i) close said first opening by said second container and (ii) close said second opening by said first container, with a movement of said movable portion away from said abutting portion.
7. A gloss processing apparatus according to claim 6 , wherein said closing mechanism includes a first urging portion configured to urge said first container toward said second container and a second urging portion configured to urge said second container toward said first container.
8. A gloss processing apparatus according to claim 3 , wherein said movable portion includes a tapered portion at an end which is abutted to said abutting portion.
9. A gloss processing apparatus according to claim 3 , wherein said abutting portion includes a tapered portion at an end which is abutted to said movable portion.
10. A gloss processing apparatus according to claim 3 , wherein said film cartridge includes:
a hooked portion provided in either one of said first container and said second container; and
a hooking portion provided in the other one of said first container and said second container and configured to engage with said hooked portion to (i) close said first opening by said second container and (ii) close said second opening by said first container,
wherein said hooking portion is elastically deformable to permit release of an engagement with said hooked portion with a mounting operation of said film cartridge to said main body.
11. A gloss processing apparatus according to claim 10 , wherein said main body includes a force applying portion configured to apply a force for elastically deforming said hooking portion to permit the release of the engagement with the mounting operation of said film cartridge.
12. A gloss processing apparatus according to claim 3 , wherein said film cartridge includes a urging portion configured to urge said first container and said second container toward each other to (i) close said first opening by said second container and (ii) close said second opening by said first container.
13. A gloss processing apparatus according to claim 3 , wherein said film cartridge includes a connecting tape configured to connect said first container and said second container to (i) close said first opening by said second container and (ii) close said second opening by said first container.
14. A gloss processing apparatus according to claim 13 , wherein said movable portion includes a cutting portion configured to cut said connecting tape with the moving operation of said movable portion to permit movement of said first container and said second container away from each other.
