Patent Number: 7,231,157

Title: Image forming apparatus

Abstract: The image forming apparatus includes a rotatable image bearing member, a latent image forming device, a developing device, a transferring device, and a corona charging device having a discharge wire and a surrounding shield member and being arranged downstream of a developing position on the image bearing member with respect to its rotational. A density detecting member detects a density of the toner image on the image bearing member at a position downstream of a discharge position of the corona charging device with respect to the rotational direction and upstream of a transfer position. An air flow path is formed through the inside of the shield member and an air is sucked from the image bearing member side toward the shield member. Toner scattered from the developing device side and headed to the density detecting member can be reduced, and ozone near a post charging device can be removed.
