ABSTRACT:
A charging and exposing head for use in an electrophotographic apparatus includes a charging and exposing chamber having a light transmission window for carrying out charging and exposing operation on an electrophotosensitive member moving along the light transmission window. In the charging and exposing head, a retaining member presses the electrophotosensitve member against the light transmission window to maintain the flatness of the electrophotosensitive member, and cooling air is supplied from a cooling gas supply pipe toward the electrophotosensitive member brought opposite to the light transmission window to prevent thermal deformation of the electrophotosensitive member.
