ABSTRACT:
An LED array printhead comprises a head substrate which carries an array of semiconductor LED chips and an array of drive IC's in corresponding relation to the LED chips. Each of the LED chips has a plurality of light emitting portions. The printhead further comprises a transparent resin coating for covering at least the LED chip array. The resin coating is provided with at least one convex lens portion at a position corresponding to a selected light emitting portion of the LED whose luminance is lower than a predetermined level.
