Abstract
In a case where a developer bottle is not attached to a bottle attachment portion, a movable support portion is kept to be at a support position, by an elastic force of a second spring, at which to support the bottle attachment portion to be higher than a reference level in position. In a case where the developer bottle is attached to the bottle attachment portion, a movable arm portion extending from the movable support portion toward an attachment space contacts the developer bottle and is displaced to outside the attachment space, which causes the movable support portion to be displaced from the support position to a release position at which to release a support of the bottle attachment portion. A control portion prohibits an image forming process when the position of the bottle attachment portion is not equal to or lower than the reference level.
