Storage assembly and mountable unit

A storage assembly,

• wherein the storage assembly is configured to be mounted in an imaging device having an electrical contact point, separately from a developing cartridge comprising a rotatable developing roller extending in a first direction;
• wherein the storage assembly comprises:
• a chip configured to store information of the developing cartridge, the chip having an electrical contact surface configured to electrically connect to the electrical contact point;
• and
• a holder configured to support the chip;
• wherein the electrical contact surface is spaced apart from the developing roller in the first direction when the storage assembly and the developing cartridge are mounted in the imaging device.

A mountable unit, comprising

• a storage assembly and a developing cartridge,
• wherein the developing cartridge is configured to be mounted in an imaging device having an electrical contact point, separately from the storage assembly;
• wherein the imaging device comprises a first accommodating area and a second accommodating area;
• wherein the developing cartridge is accommodated in the first accommodating area, and the storage assembly is accommodated in the second accommodating area;
• wherein the first accommodating area and the second accommodating area are adjacent to each other in a first direction;
• wherein the first accommodating area comprises a photosensitive drum, and the second accommodating area comprises an electrical contact point;
• wherein the storage assembly comprises a chip with an electrical contact surface, and the chip is configured to store information of the developing cartridge;
• wherein the developing cartridge comprises:
• a casing configured to accommodate developer;
• and
• a developing roller rotatable about a developing roller axis extending in the first direction;
• and
• wherein the electrical contact surface is spaced apart from the developing roller in the first direction when the developing cartridge and the storage assembly are mounted in the imaging device.
