Abstract
An optical writing device including: a current-driven light-emitting element; a thin film transistor configured to supply the light-emitting element with a drive current based on a luminance signal to put the light-emitting element in an on state; and a controller configured to, for each line of an image page, correct a first value of the luminance signal to yield a second value of the luminance signal, and to supply the thin film transistor with the luminance signal at the second value. The second value compensates for a light amount fluctuation of the light-emitting element that is dependent upon an emission/non-emission history, from an initial line of the image page to the line, of a first continuous period where the light-emitting element is kept in the on state and a second continuous period where the light-emitting period is kept in an off state.
