Abstract

Abstract PURPOSE:To make uniform the temperature distribution between heating and pressurizing rollers when carrying out the copying action by pushing the printing button for the first time by making the paper feeding interval longer before a specified number has been finished copying, and executing the copying action at the normal paper feeding interval after the finishing of copying. CONSTITUTION:The warming up after the connection of an electric power source, is carried out without rotating the heating roller 41 and the pressurizing roller 45 of a fixing device 28, but by only turning on a fixing heater lamp 44, and completing when the roller 41 is detected to have reached a target fixing temperature by a fixing thermistor 48, to assure silence during a warming up. After that, when the printing button is pushed for the first time to carry out the copying action, that is to say first thing in the morning, the paper feeding interval is made longer until a specified number of copies have been finished copying, and carrying out the copying action with normal paper feeding interval after the copying is completed, making uniform the temperature distribution between the two rollers by the heat conduction generating from the rotation of the roller 41 and the roller 45, which is in contact with it, while copying paper is not fed, assuring good fixability.
