Abstract:
An image forming apparatus includes an image bearing member for carrying a toner image, a transferer supplied with a voltage to transfer a toner image from the member onto a recording material in a transfer portion, heaters with different heating conditions for heating the image transferred onto the material, a refeeder for refeeding the material to the transfer portion to transfer the image onto the material having the image fixed by the heater, a selector for selecting the glossiness of the image after fixing, a device for determining the heater to heat the image from the heaters in accordance with the glossiness selected by the selector, and a device for changing the voltage for transferring the image onto the refed material in accordance with the heater having heated the image on the material prior to the material being refed by the refeeder.
