摘要：
A developing unit includes: a developer carrying member that visualizes an electrostatic latent image held on an image carrying member using magnetic developer; a peeling member that peels off the magnetic developer held on the developer carrying member by a magnetic force; and a movement controller that controls movement of the peeling member, when the peeling member peels off the magnetic developer, the movement controller moving the peeling member to a position close to the developer carrying member, and when the peeling member has peeled off the magnetic developer, the movement controller moving the peeling member to a position away from the developer carrying member.
