  • Toner image-fixing device
    Patent number: 4121888
    Abstract: An record medium bearing toner images is intermittently moved at different speeds toward a fixing unit including a flash lamp. Each time one portion of the record medium occupies the effective fixing section of its run for the lamp as determined by a sensor device, the flash lamp is lighted to fix the toner images on that portion of the record medium. This fixing is repeated with the succeeding portions of the record medium until all the toner images on the record medium are successively and continuously fixed.
