Fixing device preventing excessive increase in temperature

摘要

A fixing device (1) includes a rotatable fixing member (2) having a predetermined thermal storage capacity, a first heating source (6) to heat the fixing member (2), and a rotatable pressing member (5) to be in press-contact with the fixing member (2) to form a fixing region through which a sheet-like recording medium having an unfixed image thereon passes to fix the unfixed image by heat and pressure. The first heating source (6) is turned off a first predetermined time before a trailing edge of a last sheet-like recording medium in a sequence of jobs passes through the fixing region.
