摘要： A toner is proposed which includes toner particles and a fluidity-imparting agent and have such characteristics that the toner particles has an average circularity of 0.93 to 0.97, and that a residue of the toner is in an amount of 10 mg or less when 100 g of the toner is sieved with a 500-mesh sieve, which toner is for use in an electrophotographic image formation method using an intermediate image transfer method. A full-color image formation method, using this toner, and an image formation apparatus in which this toner is used are also proposed.
