The present invention addresses the problem of providing an image formation method in which faulty cleaning of a transfer material transportation belt does not occur and the image density and the toner consumption amount are favorable. The present invention pertains to an image formation method in which at least four colors of electrophotography cartridges are arranged in tandem in relation to a transfer material transportation body, wherein, taking the fixing-step-side of the transfer material transportation body is to be the downstream side and the cleaning step-side of the transfer material transportation body to be the upstream side, the total amount of a specific external additive in the toners of the electrophotography cartridge of each of the colors is adjusted to a specific amount, and a specific amount of a specific external additive is used in the toner provided to the most downstream electrophotography cartridge. |
