Abstract: An image forming apparatus includes a reception unit to receive a job, heating and pressing rotary members to form a nip portion, and a spraying member having a nozzle and a cylinder. The nozzle discharges air to the heating rotary member and a recording material. During a period after the reception unit receives the job and before a leading edge of a first sheet of the recording material reaches the nip portion, the spraying member performs a spraying operation of spraying air in an amount greater than or equal to a predetermined amount. The air that the spraying member sprays on the first sheet of the recording material during the job is higher in temperature than the air that the spraying member sprays during the period after the reception unit receives the job and before the leading edge of the first sheet of the recording material reaches the nip portion.
