The image forming apparatus further includes a control unit for supplying printing data to the plurality of the removable developing units in timings shifted form row to row.

Abstract: A nonaqueous secondary electrolytic battery comprising an electricity-generating element formed by spirally winding a laminate of a positive electrode plate, a separating material and a negative electrode plate, and an electrolytic solution with which the separating material, if it is a separator, is impregnated. The electricity-generating element is sealed in a battery case formed by a resin-laminated sheet comprising a metal layer as a barrier layer. Only a pair of lead terminals are drawn to the exterior of the battery case. The resin sheet comprises an oriented resin layer laminated on both surfaces of the metal layer. The inner heat-fused layers are opposed and heat-fused to each other. A molten and solidified resin mass is formed protruding from the inner end of the welded portion toward the inner space of the battery by 0.1 mm or more. Alternatively, the welded portion is formed thinner at the outer end thereof than at the inner end thereof.

Abstract: In a serial printer a pinion and a rack for lateral movement of a carriage, a dislodging member with edges proximate to the rack is provided to remove any chads or other foreign matters that may be attached to the rack, as they approach the pinion with the lateral movement of the carriage. The chads or other foreign matters are prevented from being caught between the pinion and the rack, and noises and increase in the torque due to the rolling in is prevented.

Abstract: A multicolor ink ribbon for use with a dot impact printer includes at least three layers. The layers include an ink layer composed of at least one colored ink ribbon having a first surface which forms a printing surface of the multicolor ink ribbon, an intermediate barrier layer having a first surface which covers a second surface of the ink layer, for preventing ink penetration from the ink layer therethrough, and a protective layer having a first surface which covers a second surface of the intermediate barrier layer and having a second surface which forms a printing head surface of the multicolor ribbon. The intermediate barrier layer prevents ink penetration from the ink layer into the protective layer, and the protective layer protects the intermediate barrier layer from physical deterioration due to impact from a printing head during use.
