摘要： 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.

摘要： An optical writing device adopting a low cost and simple structure can obtain temperatures of light emitting elements. The device comprises a plurality of light emitting elements arranged linearly in a main scanning direction. The amount of light emitting of the light emitting elements changes by self-generated heat. The light emitting elements are divided into a plurality of groups. Each of the groups includes a prescribed number of light emitting elements. The device comprises a control unit for calculating the amount of heat generation of the light emitting elements for each of groups from clock time t0 to clock time t0+Δt. The control unit calculates the temperature for each of the groups at the clock time t0+Δt, based on the amount of heat generation from the clock time t0 to the clock time t0+Δt and the temperature at the clock time t0.
