Belt having a meandering prevention guide and image forming apparatus having the same
A belt configured to travel a continuous track may be incorporated for use in an image forming apparatus. The belt may include a guide member formed on a surface of the belt to prevent a belt from meandering off of the track, where the guide member may include a rubber sheet and a carbon black material having a primer particle diameter ranging from about 15 nm to about 35 nm. An image forming apparatus incorporating the belt with one or more guide members has an increased resistance to abrasion and mitigates belt meandering and image contamination.
1. A guide member for use with a belt, formed on an inner side surface of the belt configured to prevent a belt meandering from a track, the guide member comprising a rubber sheet and a carbon black material and having a composition different from a composition of the belt,
wherein the carbon black material has a primer particle diameter ranging from about 15 nm to about 35 nm.
2. The guide member of claim 1 , wherein the carbon black material is a compound of two or more of materials selected from the group of Super Abrasion Furnace (SAP) carbon black, Super Abrasion Furnace-High Structure (SAF-HS) carbon black, Intermediate Super Abrasion Furnace (ISAF) carbon black, Intermediate Super Abrasion Furnace-High Structure (ISAF-HS) carbon black and High Abrasion Furnace (I-IAF) carbon black.
3. The guide member of claim 1 , wherein the rubber sheet comprises the carbon black material in an amount ranging from about 20 phr to about 40 phr.
4. The guide member of claim 1 , wherein the belt comprises one of a photosensitive belt, a fusing belt and a transfer belt.
5. A belt for use in an image forming apparatus, the belt configured to travel a continuous track, the belt comprising:
a guide member formed on a surface of the belt configured to prevent the belt from meandering off of the track and having a composition different from a composition of the belt,
wherein the guide member comprises a rubber sheet and a carbon black material having a primer particle diameter ranging from about 15 nm to about 35 nm.
6. The belt of claim 1 , wherein the carbon black material comprises a specific surface area of nitrogen absorption ranging from about 100 mg 2 /g to about 150 mg 2 /g.
7. The belt of claim 1 , wherein the carbon black material comprises a compound of two or more of materials selected from the group of Super Abrasion Furnace (SAF) carbon black, Super Abrasion Furnace-High Structure (SAF-HS) carbon black, Intermediate Super Abrasion Furnace (ISAF) carbon black, Intermediate Super Abrasion Furnace-High Structure (ISAF-HS) carbon black and High Abrasion Furnace (HAF) carbon black.
8. The belt of claim 1 , wherein the rubber sheet comprises one of a polycarbonate urethane rubber sheet and a polyester urethane rubber sheet.
9. The belt of claim 1 , wherein the rubber sheet comprises the carbon black material in an amount ranging from about 20 phr to about 40 phr.
10. The belt of claim 1 , wherein the belt comprises one of a photosensitive belt, a fusing belt and a transfer belt.
11. An image forming apparatus, comprising:
a belt configured to travel a continuous track;
a driving roller configured to drive the belt; and
a supporting roller configured to support the belt,
wherein the belt includes a guide member formed on a surface of the belt configured to prevent the belt from meandering off of the track and having a composition different from a composition of the belt,
wherein the guide member comprises a rubber sheet and a carbon black material having a primer particle diameter ranging from about 15 nm to about 35 nm.
12. The image forming apparatus of claim 11 , wherein the carbon black material comprises a compound of two or more of materials selected from the group of Super Abrasion Furnace (SAF) carbon black, Super Abrasion Furnace-High Structure (SAFFHS) carbon black, Intermediate Super Abrasion Furnace (ISAF) carbon black,
Intermediate Super Abrasion Furnace-High Structure (ISAF-HS) carbon black and High Abrasion Furnace (I-IAF) carbon black.
13. The image forming apparatus of claim 11 , wherein the rubber sheet comprises the carbon black material in an amount ranging from about 20 phr to about 40 phr.
14. The image forming apparatus of claim 11 , wherein the belt comprises one of a photosensitive belt, a fusing belt and a transfer belt.
15. The image forming apparatus of claim 11 , wherein the belt comprises:
a reinforcement structure configured to prevent wearing of the belt, the reinforcement structure formed on an edge where the belt is in contact with the driving roller or the supporting roller,
wherein the reinforcement structure comprise a reinforcement tape material.
16. The image forming apparatus of claim 11 , wherein the driving roller comprises a groove formed on an edge thereof, wherein a contour of the guide member corresponds to the groove for engagement between the driving roller and the guide member.
17. The belt image forming apparatus of claim 11 , wherein the supporting roller comprises a groove formed on an edge thereof, wherein a contour of the guide member corresponds to the groove for engagement between the supporting roller and the guide member.
