摘要:
A method for developing electrostatic latent images formed on an electrostatic image bearing member, particularly by a thin and uniform layer of toner formed on a toner carrying member. In the method, good images can be stably obtained by controlling the packing density within the range of 0.1 to 0.6 g/cm.sup.3 with respect to the toner layer carried on the toner carrying member at the developing station.

摘要:
An unsealing method for unsealing a packaging structure for a liquid container in which the packaging structure includes a covering member having an air vent sealing portion, a liquid supply sealing portion, and a connecting region which covers a connecting side of the liquid container and which connects the air vent and liquid supply scaling portions. The liquid supply sealing portion effects non-adhering sealing, and the connecting portion provides resistance against unsealing of the liquid supply portion. The covering member also has first and second regions which respectively include first and second resistance generation portions for generating resistance against unsealing. According to the unsealing method, the air vent is unsealed, the first resistance generating portion is separated from the liquid container, the liquid supply portion is unsealed, and the second resistance generating portion is separated. By virtue of this arrangement, the liquid container can be unsealed methodically without unexpected unsealings.

A packaging structure for a liquid container including a liquid containing portion accommodating liquid, a liquid supply portion for supplying the liquid to an outside and an air vent for fluid communication with an ambience, the packing structure includes a covering member for covering and sealing the liquid supply portion and the air vent; the covering member including; an air vent sealing portion for sealing the air vent and a liquid supply portion sealing portion for sealing the liquid supply portion and a connecting region for covering a connecting side of the liquid container which connects the air vent sealing portion and the liquid supply portion sealing portion, wherein the liquid supply portion sealing portion effects non-adhering sealing for the liquid supply portion, and the connecting region provides a resistance against unsealing of the liquid supply portion.
摘要:
A liquid discharging method for a liquid head discharge head. The head has discharge ports, liquid flow paths, bubble generating areas, bubble generating means, liquid supply ports connecting the flow paths with a common liquid supply chamber, and a movable member in the flow paths supported with a minute gap to the supply ports. The area of the movable member surrounded at least by its free end and both sides continued therefrom is larger than the opening area of the supply ports. The method includes the step of setting a period for the movable member to substantially close the opening area during the period from the application of a driving voltage to the bubble generating means to the substantial termination of isotropical growth of the entire bubble by the bubble generating means. Growth of the bubble component in the direction opposite the discharge port can be suppressed, improving liquid refill.

An ink jet recording head is provided with a plurality of discharge ports for discharging recording liquid, a discharge port plate having the discharge ports therefor, a liquid chamber for retaining the recording liquid, a plurality of discharge energy generating elements for discharging the recording liquid, a substrate having the plurality of discharge energy generating elements on one surface thereof, and a plurality of liquid flow paths extended in one direction for communicating the liquid chamber and the discharge ports, the liquid flow paths including the discharge energy generating elements therein and having the rectangular sectional configuration. The sectional shape of each of the discharge ports is circular on the end portion thereof on the recording liquid discharge side and the sectional area of the discharge port end portion connected with the liquid flow path being larger than that of the end portion of discharge port on the recording liquid discharge side, and the sectional shape of the discharge port is rectangular, while the discharge port is tapered to change the sectional shape thereof from being rectangular to circular. This ink jet recording head is effective in discharging recording liquid stably at higher speeds to form images in higher precision.
