Abstract: An image forming apparatus and a developing control method of the image forming apparatus are provided to prevent a wrap jam generated by an image printed within the front end margin of a printing medium by performing printing to lower the density of an image's front end portion, thereby varying the arrangement of the image by securing an additional margin. An image forming apparatus comprises a developing unit(120), a developing voltage apply unit(150), and a control unit(160). The developing unit attaches toner to the electrostatic latent image of a photosensitive medium(110) by a potential difference. The developing voltage apply unit applies a developing voltage to the developing unit to generate the potential difference between the photosensitive medium and the developing unit. The control unit controls the developing voltage apply unit to apply a first developing voltage to a latent image corresponding to a region from the front end of an image to be transferred to a printing medium(P) to a predetermined position and to apply a second developing voltage to the latent image corresponding to a region after the above region.
