Photosensitive member cartridge and process cartridge

A cartridge detachably mountable to a main assembly of an image forming apparatus, the cartridge comprising:

• a first unit including a rotation member configured to carry toner and rotate about a rotational axis;
• and
• a second unit detachably mountable to the first unit, the second unit including an accommodating portion accommodating the toner and a memory storing information, the memory including a contact,
• wherein in a state in which the cartridge is mounted to the main assembly (i) the memory is provided on a bottom surface of the second unit mounted to the first unit and (ii) a surface having the contact is inclined downward toward the rotation member as seen in a direction of the rotational axis of the rotation member, and
• wherein, when the first unit is oriented in a mounting posture in which the cartridge is mounted to the main assembly, the second unit is capable of taking first and second postures with respect to the first unit, the second posture being a posture in which the memory is in a position above a position in which the memory is in when the second unit takes the first posture, and
• wherein the second unit is configured to be transitioned from the second posture toward the first posture by a rotation of the second unit with respect to the first unit about a rotational axis extending along the direction of the rotational axis of the rotation member.

A cartridge detachably mountable to a main assembly of an image forming apparatus, the cartridge comprising:

• a first unit including a rotation member configured to carry toner and rotate about a rotational axis, and a pressing member;
• and
• a second unit detachably mountable to the first unit, including an accommodating portion accommodating the toner, a memory storing information, and a pressed portion,
• wherein in a state in which the cartridge is mounted to the main assembly, the memory is provided on a bottom surface of the second unit mounted to the first unit,
• wherein, when the first unit is oriented in a mounting posture in which the cartridge is mounted to the main assembly, the second unit is capable of taking a first posture and a second posture with respect to the first unit, the second posture being a posture in which the memory is in a position above the position in which the memory is in the first posture, and
• wherein the second unit is configured to be transitioned from the second posture toward the first posture by a rotation of the second unit about a rotational axis extending along the direction of the rotational axis of the rotation member, and the pressing member presses the pressed portion of the second unit to maintain the second unit at the first posture.
