  • Publication number: 20190286039
    Abstract: An image forming apparatus includes a toner cartridge, a developer, and a processor. The toner cartridge includes an accommodation container accommodating toner and a memory storing a first toner residual amount display threshold value. The developer performs development by the toner supplied from the toner cartridge. The processor calculates a second toner residual amount display threshold value based on a toner supply index, indicating an amount of the toner supplied to the developer from at least one toner cartridge used before a toner cartridge mounted on the image forming apparatus, and the first toner residual amount display threshold value. The processor outputs notification relating to a toner residual amount when a toner supply index indicating an amount of toner supplied to the developer from the toner cartridge mounted on the image forming apparatus exceeds the second toner residual amount display threshold value.

  • Publication number: 20180259886
    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 (105 Pa·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.
