Abstract
A cooling mechanism for a photoreceptor includes: a photoreceptor of cylindrical shape; a pair of flanges respectively attached to both ends in an axial direction of the photoreceptor; a rotational shaft that is inserted into a shaft center of the photoreceptor; a holder that is disposed to face a first flange and rotatably supports the rotational shaft; and a main body frame that supports the holder. In such a cooling mechanism for a photoreceptor, an air duct is configured by the through hole formed in the flange and the concave portion formed on the holder, and discharges air flow generated inside the photoreceptor to the outside thereof.
