摘要：An image forming apparatus for performing a copier job and a printer job includes a controller operatively connected to a fixing rotary body heater and a pressing rotary body heater to control the fixing rotary body heater and the pressing rotary body heater. The controller activates a standby mode after the copier job and the printer job are finished in which the controller turns off at least the fixing rotary body heater and a subsequent off mode in which the controller turns off the pressing rotary body heater and the fixing rotary body heater, and identifies which of the copier job and the printer job is to be performed to turn on and off the pressing rotary body heater in the standby mode according to the identified job.

主权项：1. An image forming apparatus for performing a copier job and a printer job, comprising: a control panel to receive the copier job; a reader to read an image on an original document to generate image data in the copier job; an image forming device to form a toner image on a recording medium according to the image data generated by the reader in the copier job or image data sent from an external device in the printer job; a media tray to contain the recording medium to be sent to the image forming device; a fixing device to fix the toner image formed by the image forming device on the recording medium, the fixing device including: a fixing rotary body rotatable in a predetermined direction of rotation;a pressing rotary body rotatable in a direction counter to the direction of rotation of the fixing rotary body and pressed against the fixing rotary body to form a nip therebetween through which the recording medium bearing the toner image passes;a fixing rotary body heater disposed opposite the fixing rotary body to heat the fixing rotary body; anda pressing rotary body heater disposed inside the pressing rotary body to heat the pressing rotary body; and a controller operatively connected to the fixing rotary body heater and the pressing rotary body heater to control the fixing rotary body heater and the pressing rotary body heater, the controller activating a standby mode after the copier job and the printer job are finished in which the controller turns off at least the fixing rotary body heater and a subsequent off mode in which the controller turns off the pressing rotary body heater and the fixing rotary body heater, and identifying which of the copier job and the printer job is to be performed to turn on and off the pressing rotary body heater in the standby mode according to the identified job.
