Abstract
A charging device including: a first charger which charges a member to be charged, the first charger having conducting particles which come into contact with the member to be charged; a second charger which charges the member to be charged in a same polarity as charging polarity of the first charger on an upstream side of the first charger in a moving direction of the member to be charged; and a controller which controls application of a charging voltage to the first charger, in which the controller turns a charging voltage on or off in an area of the member to be charged which is not subjected to charging by the second charger.
