Abstract:
An exposure device for exposing an image supporting body, comprising:a driver element; a light emitting diode microchip connected to said driver element by wires and having a light emitting diode array for outputting light for exposure; and an image forming lens for directing the light output from said light emitting diode array of said light emitting diode microchip onto an image supporting body as exposure light; said image forming lens being disposed in such a posture that the center line of said image forming lens is out of axial alignment with the center line of intensity distribution of the light output from said light emitting diode array on an incidence surface of said image forming lens, a center of rotation of said image supporting body being disposed off an extension of the center of intensity distribution of the last-named light output from said light emitting diode array; said image forming lens assuming a posture such that possible incidence of stray light is reduced when local part of the light output from said light emitting diode array reflects on said wires.
