Abstract
An optical print head for forming an electrostatic latent image on a photosensitive body, including: current-driven light-emitting elements disposed in a line shape; an indicator circuit that outputs indicator current indicating light emission amounts to the light-emitting elements; and for each light-emitting element: a holding circuit that, during a main scanning period, accumulates indicator current during a sample period to generate an indicator potential and holds the indicator potential during a hold period; and a drive circuit that supplies drive current to the light-emitting element according to the indicator potential, wherein each of the sample periods is divided into writing periods, and each of the holding circuits holds the indicator potential corresponding to the holding circuit according to a total of indicator current amounts in the sample period corresponding to the holding circuit, the indicator current amounts each indicative of indicator current during one of the writing periods.
