IMAGE FORMING APPARATUS AND LIGHT EMITTING DEVICE
First Claim
1. An image forming apparatus comprising:
- an exposer having a plurality of light emitting devices, a light emitting device among the plurality of light emitting devices to transmit light toward a photosensitive drum; and
a developer to develop an electrostatic latent image formed on a surface of the photosensitive drum by the light,whereinthe light emitting device among the plurality of light emitting devices includes;
a light emitting layer to generate the light; and
a reflective layer to reflect at least a portion of the generated light, andthe reflective layer includes a plurality of sub-reflective layers, in whicha thickness of at least one sub-reflective layer among the plurality of sub-reflective layers is different from a thickness of another sub-reflective layer among the plurality of sub-reflective layers, and/ora refractive index of at least one sub-reflective layer among the plurality of sub-reflective layers is different from a refractive index of another sub-reflective layer among the plurality of sub-reflective layers.

Abstract
An image forming device comprises: an exposer having a plurality of light emitting devices, a light emitting device among the plurality of light emitting devices to transmit light toward a photosensitive drum; and a developer to develop an electrostatic latent image formed on a surface of the photosensitive drum by the light, wherein the light emitting device among the plurality of light emitting devices includes: a light emitting layer to generate the light; and a reflective layer to reflect at least a portion of the generated light. The reflective layer can include a plurality of sub-reflective layers, in which a thickness of a sub-reflective layer among the plurality of sub-reflective layers is different from a thickness of another sub-reflective layer among the plurality of sub-reflective layers, and/or a refractive index of a sub-reflective layer among the plurality of sub-reflective layers is different from a refractive index of another sub-reflective layer among the plurality of sub-reflective layers.
