IMAGE FORMING APPARATUS

摘要

In accordance with one embodiment, an image forming apparatus comprises a heating member configured to heat a recording medium, on the surface of which a toner image is carried, to fix the toner on the recording medium; a pressing member configured to contact with the recording paper from the back side of the recording paper; an induction heating section configured to heat the heating member through induction heating; a temperature sensor configured to detect the temperature nearby the heating member; a driving control section configured to carry out a control based on the temperature detected by the temperature sensor so that the temperature of the heating member based on the induction heating section is within an allowable temperature range; a temperature range setting section configured to set the allowable temperature range so that the allowable temperature range is narrowed as time elapses from the start of a fixing processing.

1. An image forming apparatus, comprising:
a heating member configured to heat a recording medium, on the surface of which a toner image is carried, to fix the toner on the recording medium; a pressing member configured to contact with the recording paper from the back side of the recording paper; an induction heating section configured to heat the heating member through induction heating; a temperature sensor configured to detect the temperature nearby the heating member; a driving control section configured to maintain at least a standard setting temperature during a predetermined time from the start of a fixing processing and to carry out a control based on the temperature detected by the temperature sensor so that the temperature of the heating member based on the induction heating section is within an allowable temperature range; and a temperature range setting section configured to set the allowable temperature range so that the allowable temperature range is narrowed based on time elapsed from the start of the fixing processing.
