Image Forming Apparatus Having Photosensitive Drum and Transfer Belt |
| 摘要 |
In an image forming apparatus, when a photosensitive drum is mounted to the main body, the photosensitive drum is disposed below a positioning member and a transfer belt is disposed above the photosensitive drum. A first urging member urges downward an end of the photosensitive drum that is defined in an axial direction of the first photosensitive drum. A second urging member urges the photosensitive drum when the photosensitive drum is mounted to the main body. The second urging member urges the photosensitive drum upward against an urging force of the first urging member, thereby causing the photosensitive drum to make contact with the positioning member. The first urging member is disposed at a position between the positioning member and the second urging member in the axial direction of the photosensitive drum. |

1. An image forming apparatus, comprising:
a main body having a positioning member; a first photosensitive drum detachably mountable to the main body, the first photosensitive drum being disposed below the positioning member when the first photosensitive drum is mounted to the main body; a transfer belt that is disposed above the first photosensitive drum when the first photosensitive drum is mounted to the main body; a first urging member configured to urge an end of the first photosensitive drum downward, the end of the first photosensitive drum being defined in an axial direction of the first photosensitive drum; and a second urging member that is configured to urge the first photosensitive drum when the first photosensitive drum is mounted to the main body, the second urging member being configured to urge the first photosensitive drum upward against an urging force of the first urging member, thereby causing the first photosensitive drum to make contact with the positioning member, the first urging member being disposed at a position between the positioning member and the second urging member in the axial direction of the first photosensitive drum. |
