摘要:
An image forming system utilizing a light emitting diode (LED array) having LEDs arranged along a curved line. The LEDs are either edge emitting type LEDs or surface emitting type LEDs. The LEDs of the LED array emit light towards a center or optical axis of the lens. A plurality of lenses are connected together to form a lens array. Alternatively, two lens arrays can be utilized. If two lens arrays are utilized, each of the lenses in the lens array includes an aspherical surface. The curved LED array prevents the flaring of light and produces an even pattern of light emission on a light receiving surface such as a photoconductive drum.
