  • Patent number: 8478184
    Abstract: An image forming apparatus includes a transfer unit configured to transfer a toner image based on image data onto a recording medium, a fixing device configured to thermally fix the toner image transferred onto the recording medium, a stack tray configured to stack a recording medium conveyed from the fixing device, and a controller configured to calculate based on the image data an amount of a toner on a top surface of the recording media stacked on the stack tray and an amount of a toner on a bottom surface of the recording media to be subsequently conveyed and discharged onto the stack tray and to control a recording medium discharge interval based on a result of calculating the amounts of the toners.

  • Patent number: 8224201
    Abstract: An image heating apparatus includes an endless belt configured to heat a toner image on a recording material, a heater configured to heat the endless belt, a voltage supplier configured to supply an alternating voltage to the heater, a temperature detector configured to detect a temperature of the heater, a controller configured to control a ratio of a time during which the voltage is supplied to the heater to a period at which the voltage is supplied to the heater according to the temperature detected by the temperature detector, and a regulator configured to regulate a maximum value of the ratio according to the temperature detected by the temperature detector by varying the voltage supplied to the heater at a predetermined period.

  • Patent number: 8032044
    Abstract: An image forming apparatus capable of preventing toner fusion between recording sheets, with a construction that does not require increase in cost and size of the apparatus and does not unduly lower productivity, to thereby offer high usability. For image formation on plural pieces of recording sheets, a CPU controls a recording sheet conveyance interval for a first set based on a detected amount of toner used for the image formation on each page, stores the toner use amounts for respective pages of the first set into a RAM, and controls the recording sheet conveyance interval for second and subsequent sets based on the toner use amount stored in the RAM for each page.

  • Patent number: 7826762
    Abstract: An image forming apparatus capable of preventing toner fusion between recording sheets to thereby offer high usability, with a construction that does not cause increase in cost and size of the apparatus and an undue reduction in productivity. In the image forming apparatus, a toner use amount in a partial region of an toner image transferred from an intermediate transfer belt to a recording sheet is detected. When it is determined that the toner use amount detected for the partial region is equal to or greater than a predetermined amount, a recording sheet conveyance interval is widened.
