Abstract
A method for forming a fixed toner image includes maintaining a fixing device temperature at a standby temperature, and after wake-up from the standby state, forming an unfixed toner image on a sheet using a low melting point toner. The difference between temperatures that cause a viscosity of the toner in first and second conditions to be 1.0 (10Pa·s) is within a range of 30° C. to 60° C., the toner in the first condition not having been maintained in a 160° C. environment for 24 hours and the toner in the second condition having been maintained in a 160° C. environment for 24 hours. The method further comprises increasing the fixing device temperature to a fixing temperature of the toner, which is higher than the standby temperature, and after the fixing device temperature has reached the fixing temperature, passing the sheet with the unfixed toner image through the fixing device.
