Image forming apparatus provided with light guide and light source

摘要

An image forming apparatus includes: a main casing; a light source; and a photosensitive cartridge. The light source is provided in the main casing and configured to emit a light. The photosensitive cartridge is mountable in the main casing in a mounting direction. The photosensitive cartridge includes: a photosensitive drum; a light guide; a first wall and a second wall. The photosensitive drum has a surface. The light guide is configured to guide the light emitted from the light source to the surface of the photosensitive drum to eliminate static on the surface of the photosensitive drum. The second wall is spaced apart from the first wall in a first direction that crosses the mounting direction. The light source is disposed between the first wall and the second wall when the photosensitive cartridge has been mounted in the main casing.

1. An image forming apparatus comprising:
a main casing; a light source provided in the main casing and configured to emit a light; and a photosensitive cartridge configured to be mounted in the main casing in a mounting direction, the photosensitive cartridge comprising: a photosensitive drum having a surface and an axis extending in an axial direction, the axial direction crossing the mounting direction; a light guide configured to guide the light emitted from the light source to the surface of the photosensitive drum to eliminate static on the surface of the photosensitive drum; a first wall; and a second wall positioned to face the first wall in the axial direction such that an imaginary line extending in the axial direction and passing through the first wall passes through the second wall, the second wall thereby being positioned to overlap the first wall when viewed in the axial direction, the light source being disposed between the first wall and the second wall when viewed along the imaginary line in the axial direction, and when the photosensitive cartridge has been mounted in the main casing.
