摘要： An image recording apparatus includes a rotating photosensitive drum, a developing unit, a neutralizing device, and a transferring device. An electrostatic latent image is formed on a charged surface of the rotating photosensitive drum, the electrostatic latent image being developed by a developing unit and subsequently transferred by a transferring device to a print medium. The neutralizing device neutralizes the charged surface of the photosensitive drum at the point on the surface disposed downstream of the developing unit and upstream of the transferring device with respect to rotation of the photosensitive drum. A controller controls the neutralizing device according to characteristics of the print medium such as size, material, insulation, and transparency. The neutralizing device may be operated in different modes. For example, the neutralizing device may neutralize an entirety of the charged surface of the photosensitive drum only if the print medium is of a predetermined characteristic, i.e., an insulating sheet such as a transparent OHP sheet or may neutralize only selected parts of the charged surface of the photosensitive drum according to a width of the print medium.
