Abstract
In an image forming apparatus, an exposure head has blue light emitting elements, a base on which the blue light emitting elements are provided, bonding pads formed on the base, and an aluminum-made reflecting layer formed on each bonding pad. Each aluminum-made reflecting layer has a reflectivity of 90% or higher to blue light from the light emitting element with respect to the regular reflection component. Part of blue light generated by one of the light emitting elements may travel to an adhered surface of the light emitting element, but it is reflected by the aluminum-made reflecting layer without being absorbed by the adjacent bonding pad, so that that part of blue light is re-directed toward a microcapsule recording sheet. This construction considerably increases the power of blue light emitted from each blue light emitting element provided in the exposure head, thereby enabling provision of an image forming apparatus in which the power of light emitted from each blue light emitting element provided in an exposure device is considerably increased.
