Patent ID: 8185001

Claim:
An image forming apparatus, comprising: an image bearing member to bear an electrostatic latent image on a surface thereof; a developing device disposed adjacent to the image bearing member to develop the electrostatic latent image formed on the image bearing member using toner to form a toner image; a transfer device to transfer the toner image onto a recording medium; a fixing device to fix the toner image; a first detector to detect at least glossiness of a surface of the recording medium; a second detector to detect at least a space between asperities on the surface of the recording medium; and a controller to control an amount of toner when forming the toner image, wherein the controller adjusts the amount of toner based on the glossiness of the recording medium detected by the first detector and the space between the asperities detected by the second detector, and wherein the controller increases the amount of toner when the glossiness detected by the first detector is equal to or greater than a predetermined value and the space between the asperities detected by the second detector is equal to or greater than a predetermined multiple of weight average particle diameter of the toner.
