Abstract
An image forming apparatus has a first recording mode of outputting the recording material without passing thru the glossiness applying device after fixing and a second recording mode using the glossiness applying device, and then outputting the recording material. In the latter recording mode (B), when a void ratio G of toner in the toner image not yet subjected to the glossing process by the glossiness applying device is defined by a thickness tof a toner layer on the recording material after fixing and before entering the glossiness applying device, and a thickness tof a toner layer on the recording material after passing through the glossiness applying device, satisfies the formula: G=100×(t-t)/t. In the recording mode (B), fixing conditions for the fixing device and the glossiness applying device are respectively set so that the void ratio of toner satisfies a formula 15≦G≦60.
