摘要： A transfer device includes a holding body, a transfer body, and a setting portion. The holding body holds multiple layers including a base layer formed of a toner having a mass larger than a threshold. The toner is electrically charged by a charging device. The transfer body transfers the layers on the holding body to a recording medium. The setting portion sets the charging device so that the charging device electrically charges a toner immediately after being transferred to the holding body with a larger amount of electric charges when the base layer is located uppermost on the holding body, than when the base layer is located other than uppermost on the holding body.

摘要： An image forming apparatus includes an endless transfer member, a first transfer section, a second transfer section, and a medium transfer section. An image is transferred to the transfer member during circulation of the transfer member. The first transfer section forms an image using a toner containing flat metallic pigment particles, and transfers the formed image to the transfer member through a transfer current. The second transfer section forms an image using a toner not containing flat metallic pigment particles, and transfers the formed image to the transfer member through a transfer current. The second transfer section is disposed upstream of the first transfer section in a circulation direction of the transfer member. The medium transfer section transfers the image transferred to the transfer member to a recording medium through a transfer current. The transfer current for the first transfer section is smaller than that for the second transfer section.

摘要： An image forming apparatus includes a first image forming portion that forms a toner image on a latent image carrier with a toner containing a flat pigment; and a second image forming portion that forms a toner image on a latent image carrier with a toner not containing the flat pigment. The toner images formed by these image forming portions are transferred to a toner image carrier or a recording medium. The average charge amount per particle of the toner containing the flat pigment is smaller than that of the toner not containing the flat pigment. A transfer width is larger than the particle diameter of the toner containing the flat pigment. A transfer current flowing between the latent image carrier of the second image forming portion and the toner image carrier or the recording medium is higher than or equal to a value required to form an electric field.
