Image forming apparatus

An image forming apparatus comprising:

• an apparatus main body to which a developing unit including a developing roller can be attached;
• an opening/closing member configured to open and close an opening through which the developing unit passes when the developing unit is detached from the apparatus main body;
• and
• a restriction member configured to restrict a movement of the developing unit attached to the apparatus main body,
• wherein the developing unit attached to the apparatus main body can move between a development position where the developing roller can attach toner to a photosensitive member, and a separate position where the developing roller is separate from the photosensitive member so that the developing roller does not attach toner to the photosensitive member, and
• wherein the opening/closing member is opened, whereby the developing unit moves to a detachment position where the developing unit can be detached from the apparatus main body and which is between the development position and the separate position, and the restriction member restricts a movement of the developing unit from the detachment position in a direction different from a detachment direction in which the developing unit is detached from the apparatus main body.

An image forming apparatus comprising:

• an apparatus main body to which a developing unit including a developing roller can be attached;
• an opening/closing member configured to open and close an opening through which the developing unit passes when the developing unit is detached from the apparatus main body;
• and
• a moving member configured to move the developing unit attached to the apparatus main body,
• wherein when the moving member presses the developing unit at a first pressing position, the developing unit is at a development position where the developing roller can attach toner to a photosensitive member, and when the moving member presses the developing unit at a second pressing position, the developing unit is at a separate position where the developing roller is further away from the photosensitive member than at the development position, and
• wherein in a case where the opening/closing member is opened when the moving member presses the developing unit at the first pressing position, the moving member releases the pressing of the developing unit, and in a case where the opening/closing member is opened when the moving member presses the developing unit at the second pressing position, the moving member releases the pressing of the developing unit.
