An optical writing apparatus includes an irradiation unit which irradiates a writing light on an optical writing image display medium comprising a photoconductor layer and a display layer, a voltage applying unit which applies an image writing pulse voltage to the display layer and the photoconductor layer, and a control unit. The control unit controls the irradiation unit such that, at a first time interval at which the writing light is irradiated, the writing light is irradiated on the photoconductor layer, and controls the voltage applying unit such that a first pulse voltage is applied at an interval which is longer than the first time interval, and such that a second pulse voltage whose polarity is opposite to a polarity of the first pulse voltage and whose absolute value is larger than an absolute value of the first pulse voltage is applied after application of the first pulse voltage.
