摘要： An optical writing device including light-emitting elements forming element arrays. The element arrays are each composed of light-emitting elements arranged in line in a main scanning direction, and reside at respective positions along a sub-scanning direction. A correction unit receives signal values in one-to-one correspondence with the light-emitting elements and performs correction to acquire corrected signal values each indicating a light amount of a corresponding light-emitting element. The correction is for eliminating a light amount difference in the main scanning direction occurring for each element array. A driving unit supplies driving currents to the light-emitting elements based on the corrected signal values, and a control unit performs a control of causing at least two element arrays to emit light for different durations within one main scanning period. The control is for eliminating a light amount difference in the sub scanning direction occurring between the at least two element arrays.

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.
