(57) Abstract: An image forming apparatus capable of obtaining a good image without glare on the front and back sides and a difference in image gloss even when using an image forming toner having an unprecedented low-temperature fixing property, particularly Provided are an image forming apparatus having a double-sided image forming mechanism, and an image forming method using the image forming apparatus. [MEANS FOR SOLVING PROBLEMS] In an image forming apparatus equipped with a double-sided image forming means, the toner used in the image forming apparatus is a toner having toner particles containing at least a binder resin, a colorant and a release agent, and inorganic fine powder. The value of the molecular weight distribution by GPC determined by the THF-soluble matter of the binder resin) has at least one peak between 1,000 and 10,000, and the half width of the distribution has a molecular weight of 15,000. And the weight% of the molecular weight of 10 5 or more is 10 wt% or less, and the chloroform-insoluble content of the toner binder resin is 5 to 5%. An image forming apparatus characterized by containing 40%. 2. An image forming method using the image forming apparatus. |
