Image forming apparatus with features that suppress deformation of door caused by counterforce from cartridge

An image forming apparatus comprising:

• a cartridge including a rotating member that carries a toner, and a positioning portion;
• and
• an apparatus main body to which the cartridge can be detachably attached in an attaching direction, the apparatus main body including,
• an opening portion through which the cartridge passes when being attached to the apparatus main body,
• an opening and closing member that is rotatable about a rotational axis extending in a direction perpendicular to the attaching direction, the opening and closing member being rotatable between a first position where the opening and closing member does not cover the opening portion and a second position where the opening and closing member covers the opening portion, the opening and closing member including an engaging portion,
• an engaged portion that is configured not to become engaged with the engaging portion when the opening and closing member is at the first position and that is configured to engage with the engaging portion while the opening and closing member moves from the first position to the second position,
• an abutment portion that, by abutting against the positioning portion of the cartridge, determines a position of the cartridge with respect to the apparatus main body in the attaching direction when the cartridge is attached to the apparatus main body, and
• a pushing member attached to the opening and closing member and configured to push the cartridge toward the abutment portion while the opening and closing member is rotating toward the second position,
• wherein when viewed in a direction of the rotational axis, the engaging portion is provided in an area of the opening and closing member between the rotational axis and an attached portion thereof to which the pushing member is attached, and is configured to be on a side opposite to the rotational axis across the engaged portion when the engaging portion engages with the engaged portion.
