Abstract
An image forming apparatus includes an image holding member; a charging unit that charges the surface of the image holding member; an electrostatic charge image forming unit that forms an electrostatic charge image on the charged surface of the image holding member; a developing unit that has an electrostatic charge image developer and that develops the electrostatic charge image on the surface of the image holding member with the electrostatic charge image developer to form a toner image; a transfer unit that transfers the toner image formed on the surface of the image holding member to a recording medium; and a fixing unit that includes a fixing belt that comes into contact with the toner image transferred to the recording medium, a rotational member that is disposed in contact with the outer surface of the fixing belt and that forms a contact area between the fixing belt and the rotational member, and a heat source that is disposed so as to face the inner surface of the fixing belt to directly heat the fixing belt, wherein the electrostatic charge image developer contains a toner that has a temperature Tat a storage modulus of G'=1×10Pa and a temperature Tat a storage modulus of G′=1×10Pa and that satisfies a condition 1 and a condition 2, and the recording medium having the transferred toner image passes through the contact area to fix the toner image to the recording medium1.215≤≤1.365  Condition 1:50° C.≤≤68° C.  Condition 2:
