Image forming apparatus having fixing device with differential pressure at outlet and inlet

摘要

A fixing device includes a fixing rotary body that heats toner while rotating and fixes the toner on a recording medium, a pressurizing rotary body that sandwiches and pressurizes the toner and the recording medium by the fixing rotary body, and a supporting part that supports the fixing rotary body from the inside so that a peak pressure on an outlet side of the recording medium becomes equal to or lower than a peak pressure on an inlet side, in a contact part where the fixing rotary body and the pressurizing rotary body come into contact with each other.
