Cartridge, toner cartridge, and image forming apparatus

An image forming apparatus comprising:

• an apparatus main assembly;
• a first cartridge configured to be detachably mounted to the apparatus main assembly in a first mounting direction, the first cartridge including (i) a developing roller configured to rotate about a first rotation axis extending in a first axial direction, (ii) a developing frame provided with a developing chamber configured to accommodate toner to be supplied to the developing roller, and (iii) a first memory configured to store information and including a first substrate and a first conductive portion, the first substrate including a first surface on which the first conductive portion is disposed, wherein, the first cartridge includes a first end and a second end opposite to the first end with respect to the first axial direction, and the first axial direction crosses the first mounting direction;
• and
• a second cartridge configured to be detachably mounted to the apparatus main assembly in a second mounting direction, the second cartridge including (i) a toner feeding member configured to rotate about a second rotation axis extending in a second axial direction, (ii) a toner frame provided with a toner chamber configured to accommodate the toner feeding member and toner to be supplied to the developing chamber, and (iii) a second memory configured to store information and including a second substrate and a second conductive portion, the second substrate including a second surface on which the second conductive portion is disposed, and wherein, the second cartridge includes a third end and a fourth end opposite to the third end with respect to the second axial direction, and the second axial direction crosses the second mounting direction,
• wherein the second cartridge is detachably mounted to the first cartridge, and
• wherein, in a state where the first cartridge and the second cartridge are mounted to the apparatus main assembly, (i) the first conductive portion is directed in the first mounting direction, (ii) the second conductive portion is directed in the second mounting direction, (iii) an angle formed by the first mounting direction and a normal direction of the first surface is less than an angle formed by a direction perpendicular to the first mounting direction and the normal direction of the first surface, and (iv) an angle formed by the second mounting direction and a normal direction of the second surface is less than an angle formed by a direction perpendicular to the second mounting direction and the normal direction of the second surface.
