Abstract: In a line head, a plurality of element arrays arranged in a first direction. Each array includes a plurality of light emission elements arrayed in a second direction which is perpendicularly to the first direction. The light emission elements emit light for forming an electrostatic latent image on a photosensitive surface of an image carrier. A switcher activates the light emission elements in at least one of the element arrays while deactivating the others. A developer develops the latent image as a visible image with toner.

Abstract: Provided is an exposure head controller that controls, via pulse width modulation control, the emission quantity of each light emitting element in an exposure head having a light emitting element array formed by arranging a plurality of light emitting elements in a main scanning direction and a sub scanning direction orthogonal thereto, comprising: a data retention unit that retains dot gathering control data showing whether to emit each light emitting element at the starting point side, terminal point side or in the middle of an emission period corresponding to a 1 pixel pitch in the sub scanning direction, or to divide and emit each light emitting element at the starting point side and terminal point side, emission time data showing the emission time of each light emitting element, and skew data showing the skew quantity of each light emitting element; a dot gathering operation circuit provided to each light emitting element and which operates the time in which the light emitting element is to be retained in a non-emission state from the starting point of the emission based on the dot gathering control data input from the data retention unit; a delay time measurement circuit that acquires the skew data from the data retention unit and acquires the non-emission time data showing the retention time in the non-emission state from the dot gathering operation circuit, adding these to seek the delay time to be set before starting the emission of the light emitting element, measuring the delay time, and outputting a prescribed signal after the lapse of the delay time; and an emission instruction circuit that outputs to a light emitting element drive circuit an emission instruction signal for instructing the emission of the light emitting element from the point in time the emission time data is acquired from the data retention unit and a prescribed signal is output from the delay time measurement circuit up to the elapse of the emission time indicated by the emission time data.
