摘要： An image forming apparatus includes a reference-pattern detecting transfer-body, a reference-pattern detecting unit, and a condition changing unit. The reference-pattern detecting transfer-body directly transfers a reference pattern image formed on an intermediate transfer body without a recording material. The reference-pattern detecting unit detects an optical reference pattern with respect to the image transferred onto the reference-pattern detecting transfer-body. The condition changing unit changes the image forming conditions based on a result of detection.

An amount of resistivity change in the first resistivity ranges from approximately 0.5 to approximately 1.5 after application of 100V and is 0.2 or smaller after application of 500V. An amount of resistivity change in the second resistivity is 0.1 or smaller after application of 100V and 500V.

摘要： An image forming apparatus includes an image carrier, an endless belt whose front surface contacts the image carrier to form a transfer nip, and a bias applying roller configured to apply a transfer bias to a back surface of the endless belt. An image is formed of a toner having an additive embedded rate of not less than 40 percent and including a mother particle having a binder resin and a colorant, and an external additive. The bias applying roller is located so as to satisfy a relationship, L>(A/2)+(B/2)+C, where A is a diameter of the image carrier, B is a diameter of the bias applying roller, C is a thickness of the endless belt, and L is a distance between centers of the image carrier and the bias applying roller on a virtual plane perpendicular to an axis direction of the image carrier.
