A cartridge detachably attachable to an apparatus body of an image forming apparatus that forms an image on a recording medium in which a memory unit is fixed by an inexpensive adhesive member that can control adhesion force. The cartridge includes: a memory; and a memory support member that supports the memory. The memory has a semiconductor device storing information related to a cartridge, a sealing material that protects the semiconductor device, and a cartridge electrical contact configured to be electrically connectable to a body electrical contact of the image forming apparatus body for transferring information on the semiconductor device to the image forming apparatus body. The sealing material and the memory support member contain the same type of a thermoplastic resin, the sealing material and the memory support member have bonding faces, and at least parts of the bonding faces are welded and fixed by a solvent.

A print head assembly includes a dynamically shifting circuit board. The circuit board is forced into a rear position toward a cavity for a print ink cartridge and is allowed to move forward away from the cavity for removal of the cartridge, which allows vertical removal and installation rather than requiring angular shifting. The circuit board may be biased in the forward direction away from the cavity and held in place by a plate. The plate is movable between two positions which respectively move the circuit board to the rear position against the bias and allow the circuit boar to move to the forward position via the bias force.
