Image forming apparatus including a movement mechanism for moving a toner container that is replaceable

An image forming apparatus comprising:

• a toner container configured to contain toner;
• and
• a main body to which the toner container is attachable and from which the toner container is detachable, the main body including
• an image forming unit including a photosensitive drum configured to bear a toner image, a toner containing portion configured to contain the toner supplied from the toner container, and a development roller configured to bear the toner contained in the toner containing portion and to supply the toner to the photosensitive drum,
• an attaching portion to which the toner container is attachable and from which the toner container is detachable,
• an opening portion through which the toner container passes when the toner container is attached to the attaching portion,
• an acquisition unit configured to acquire a correlation value that correlates with a toner remaining amount of the toner container,
• an opening/closing member configured to move between an open position in which the opening/closing member opens the opening portion and a closed position in which the opening/closing member closes the opening portion,
• a detection unit configured to detect whether the opening/closing member is at the open position or at the closed position,
• a movement mechanism configured to execute a moving operation for moving the toner container from a first position to a second position, the first position being a position where the toner is supplied from the toner container toward the toner containing portion, the second position being a position downstream from the first position in a detachment direction for detaching the toner container from the attaching portion, and
• a control unit configured to control the movement mechanism so as to execute the moving operation in a case where both of a first condition and a second condition are satisfied and so as not to execute the moving operation in a case where at least one of the first condition and the second condition is not satisfied,
• wherein the first condition is a condition in which the correlation value satisfies a predetermined condition, and the second condition is a condition in which the detection unit detects that the opening/closing member is at the open position.
