Abstract:
An image forming apparatus includes a developing unit that stores a developer containing a toner and develops an electrostatic charge image on a image holding member by the developer to form a toner image, a transfer unit that transfers the toner image on the image holding member onto a recording medium, and a fixing unit that performs an operation of heating and pressing twice or more to the toner image on the recording medium by at least one heating and pressing member which contacts with the toner image, wherein the toner has a sea and island structure of a sea portion containing a binder resin and an island portion containing a release agent, a maximum frequent value and a skewness in distribution of eccentricity B of the island portion is 0.75 to 0.95 and −1.10 to −0.50, respectively, and eccentricity B is defined in the specification.
