A liquid electrophotographic development system has a plurality of removable cartridges mounted on a rotatable support for selective engagement with an electrophotographic member to be developed. Each cartridge has a liquid developer reservoir and a flexible toner concentrate container from which concentrate is supplied to the developer in the reservoir as needed. A fluted roll pumps developer in a uniform manner from the reservoir to the electrophotographic member. After depletion of the toner concentrate and developer, any developer remaining in the cartridge can be pumped into the flexible container to prevent spillage on disposal of the cartridge. The cartridge housing has only one opening and minimum-size passages between the reservoir and the opening to inhibit evaporation of developer liquid.

Multicolor electrophotographic development system with detachable liquid

A tape transport fits within the five and one-quarter inch form factor and has motor driven mechanisms for automatically loading a DC600-type cartridge endwise therein. The transport includes a frame dimensioned to fit within the form factor, and a front panel extending across a forward transvere end of the frame. The front panel has a slot dimensioned so that the cartridge can be endwise inserted through the slot onto a tray movably supported within the frame. A read/write head is mounted to the frame adjacent the tray for reciprocating the head along an axis perpendicular to a base plate of the cartridge. A capstan drive motor is also mounted to the frame adjacent the tray so that a capstan drive roller connected to its shaft can drive a belt capstan roller of the cartridge. Guides associated with the tray permit the same to be moved by a motor driven gear box to automatically carry the cartridge rearwardly and then laterally into engagement with the read/write head and the capstan drive roller. A door opener partially opens the tape access door of the cartridge as the cartridge moves rearwardly so that when the cartridge is thereafter moved laterally the head can engage the tape.
