Abstract
A charger or other corona generating source in an image forming apparatus is ventilated by free convection. A corona charger includes a shield partially enclosing it. The shield includes an opening into an air channel, which air channel includes a portion which has an upward or vertical direction. Air in the vertical portion of the channel is heated, which causes the air to rise to an exit followed by air through the opening in the shield to ventilate the charger.
