光書き込みヘツド。[Claims for Utility Model Registration] (1) In an optical writing head that performs optical writing on a photoreceptor sensitized by bias light, a light source and a shutter pixel control the transmission of light from the light source to write on the photoreceptor. 1. An optical writing head comprising: a shutter element for optically writing on a body; and means for guiding part of the light from the light source as bias light to a photoreceptor. (2) The optical writing head according to claim 1, wherein the means for guiding the bias light to the photoreceptor is constituted by a bias light window provided in the shutter element.
