Abstract:
An image forming apparatus includes a control portion configured to output, in a test mode, a recording member which has passed through a fixing nip portion in a case of a first temperature difference in which a center part temperature of a first rotary member is higher than an end part temperature of the first rotary member and a recording member which has passed through the fixing nip portion in a case of a second temperature difference in which the center part temperature is lower than the end part temperature by one operation of starting test mode to the input portion.
