Abstract
An optical writing device performing optical writing with a light-emitting element, performing light amount switching, and including: a unit estimating a first value corresponding to a current amount for causing the element to emit a first light amount immediately after the switching; a unit supplying to the element, from immediately after the switching, a current amount corresponding to a first digital value acquired by quantizing the first value; a unit estimating a time amount through which a current amount for keeping the element emitting the first light amount increases from the current amount for causing the element to emit the first light amount immediately after the switching to a current amount corresponding to a second digital value greater than the first digital value by one step; and a unit supplying to the element, when the time amount elapses after the switching, the current amount corresponding to the second digital value.
