Abstract:
1. An image forming apparatus comprising: a photoconductor; and a corona charge device disposed adjacent to the photoconductor, wherein the corona charge device includes: a discharge pin; a shield case to support the discharge pin therein, the shield case including a first portion, a second portion arranged at a rotational downstream portion of the photoconductor so as to face the first portion, an opening facing the photoconductor, and an exhaust hole to cause suction pressure within the shield case; a first shielding member to reduce a gap between the photoconductor and an upper end of the second portion of the shield case so as to define an outside air inlet through which outside air is introduced into the shield case; a second shielding member, one end of which is coupled to a first portion of the shield case and the other end comes into contact with the surface of the photoconductor; and a guide member having a guide surface protruding from an outer surface of the second portion to guide outside air around the shield case to the outside air inlet.
