    摘要: An image formation apparatus has an image formation unit that forms toner images on an image holding member. A primary transfer unit transfers toner images on the image holding member onto an intermediate transfer member. A secondary transfer unit transfers toner images on the intermediate transfer member onto a recording medium. An electrically-grounded contact member first comes into contact with the intermediate transfer member downstream from a primary transfer portion. The relationship −2.0≦ln(Vtr)−L/(s×logρ)≦−1.0 is satisfied, in which L (mm) represents the distance from the primary transfer portion to a position where the intermediate transfer member first comes into contact with the contact member, Vtr (V) represents the absolute value of applied voltage to the primary transfer unit, s (mm/sec) represents the moving speed of the intermediate transfer member, and ρ(Ω/□) represents the surface resistivity of the intermediate transfer member.
