Patent ID: 7917051

Claim:
An image forming apparatus comprising: a photosensitive drum that rotates in a specified direction; a developing device for forming a toner image on a surface of the photosensitive drum; a transfer member for transferring the toner image from the photosensitive drum to a printing medium passing between the photosensitive drum and the transfer member; a first guide, which is disposed in a position downstream from the developing device and upstream from the transfer device with respect to the specified direction to face the photosensitive drum, for guiding the printing medium to between the transfer member and the photosensitive drum; an air flow generator for generating an air flow passing through a position different from a position where a first air flow along the surface of the photosensitive drum is generated by the rotation of the photosensitive drum; and a flow passage, which is disposed upstream from a path of the printing medium and downstream from the developing device with respect to the specified direction, for directing part of the first air flow to the second air flow.
