Abstract
A discharger is provided, which can eliminate charge from a surface of a photoconductor. The discharger includes: a light source; and a light guide member which extends in a first direction to be opposed to the surface of the photoconductor in a second direction substantially orthogonal to the first direction. The light guide member has a plurality of holes, each defined by a hole surface. At least a portion of the hole surface is curved. The hole extends in an orthogonal direction substantially orthogonal to the first and second directions.

A discharger configured to eliminate charge from a surface of a photoconductor, the discharger comprising:
- a light source;
- a light guide member which extends in a first direction across a width of the photoconductor to be opposed to the surface of the photoconductor in a second direction substantially orthogonal to the first direction, and which is configured to guide light from the light source to the photoconductor, wherein
- the light guide member has a plurality of holes, each defined by a hole surface, the hole surface being a rough surface of approximately 12.5 to 25 Rz,
- at least a portion of the hole surface is curved, and
- the hole extends in an orthogonal direction substantially orthogonal to the first and second directions.
A process cartridge to be installed in an image forming apparatus, the process cartridge comprising:
- a photoconductor;
- and
- a light guide member which extends in a first direction to be opposed to a surface of the photoconductor in a second direction substantially orthogonal to the first direction, and which is configured to guide light from a light source to the photoconductor, wherein
- the light guide member has a plurality of holes, each defined by a hole surface, the hole surface being a rough surface of approximately 12.5 to 25 Rz,
- at least a portion of the hole surface is curved, and
- the hole extends in an orthogonal direction substantially orthogonal to the first and second directions.
