Image forming apparatus

摘要

According to an embodiment, an image forming apparatus having a function to erase an image formed on a recoding medium is provided. The image forming apparatus has an operation panel which, in a first mode in which an image forming process and an erasing process are not executable, accepts selection of any mode of a second mode in which the image forming process and the erasing process are executable, and a third mode in which the image forming process is not executable and the erasing process is executable.

主权项

1. In an image forming apparatus having a function to erase an image; the image forming apparatus comprising:
an image forming unit to form an image on a recording medium; a fixing unit to heat the image at a fixing temperature to fix the image on the recording medium and heat a formed imaged at an erasing temperature higher than the fixing temperature to erase the formed image; an operation panel which, in a first mode in which an image forming process by the image forming unit and an erasing process by the fixing unit are not executable, accepts selection of any control mode of a second mode in which the image forming process and the erasing process are executable, and a third mode in which the image forming process is not executable and the erasing process is executable; a control unit which controls the image forming unit and the fixing unit in any control mode of the first mode, the second mode, and the third mode, in response to the selection of the mode of the operation panel; wherein in response to the selection of the second mode, the control unit performs a warming-up operation for execution of the image forming process and the erasing process, the warming-up operation includes a calibration operation, a registration operation, and a temperature raising operation of the fixing unit; and wherein in response to the selection of the third mode, the control unit performs the warming-up operation without the calibration operation and the registration operation.
