Abstract
Official abstract text for this publication.
A fixing device for fixing an unfixed toner image on a recording medium includes a rotatable fixing member heated by a heater to contact the recording medium bearing the unfixed toner image while rotating, with the heater disposed inside a hollow of the fixing member and turned on and off intermittently at a start of a fixing process to heat the fixing member intermittently, a first pressing member disposed opposite the fixing member to press against and rotate the fixing member to define a fixing nip through which the recording medium passes to fix the unfixed toner image with heat and pressure, and a temperature detector to detect a change in the temperature of the fixing member when the heater turns on and off intermittently. When the temperature detector detects the change in the temperature of the fixing device, the heater is turned on continuously.
First claim
Opening claim text (preview).
What is claimed is: 1. A fixing device for fixing an unfixed toner image on a recording medium, comprising: a rotatable fixing member that is locally heated by a heater to produce a temperature distribution that includes areas across the fixing member in a direction of rotation of periodically changing temperature, and which contacts the recording medium bearing the unfixed toner image while rotating; the heater disposed inside the fixing member and turned on and off intermitten…
