Abstract
An image forming apparatus includes: an image bearing member that carries a developer image; a transfer member that forms a transfer nip portion with the image bearing member and transfers the developer image in the transfer nip portion from the image bearing member to a recording material; a fixing portion that includes a heater and fixes the developer image to the recording material using heat of the heater; a temperature detection portion that detects a temperature of the fixing portion; a control portion that controls power supplied to the heater such that the temperature detected by the temperature detection portion becomes a predetermined control target temperature; and an acquisition portion that acquires a temperature of the image bearing member or the transfer member. The control target temperature is changed based on the temperature acquired by the acquisition portion.
