Abstract
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.
