Image forming apparatus capable of reducing time unable to perform image formation due to temperature change of image bearing member

摘要

An image forming apparatus is capable of reducing the time when it is unable to perform image formation due to a temperature change of an image bearing member. The apparatus includes a rotatable image bearing member; an electrostatic image forming device for continuously forming electrostatic images on the image bearing member based on forming image amount information; a toner image forming device for developing the electrostatic image and forming a toner image; a primary transferring device for transferring the toner image on the image bearing member to a rotatable intermediate transferring member; a simultaneously transferring and fixing device for transferring the toner image on the intermediate transferring member to a recording material and heating and fixing it; a detector detects a temperature of the image bearing member; and a starting device starts the electrostatic image forming means based on a detection result and the forming image amount information.
