摘要:
The present image forming apparatus forms a reference developing material image on an image carrier using an exposure unit and a developing unit before executing auto tone correction processing, and detects the density of the reference developing material image formed on the image carrier. If the detection result indicates that the toner charge amount of the developing material contained in the developing unit is within a predetermined range, auto tone correction processing is executed, whereas if the detection result of the density detecting unit indicates that the toner charge amount of the developing material contained in the developing unit is outside the predetermined range, adjustment processing for adjusting the toner charge amount of the developing material contained in the developing unit to be within the predetermined range is executed before execution of auto tone correction processing.

A magnetron has an anode cylinder, a plurality of vanes arranged radially within the anode cylinder, a magnetic piece disposed at an open end section of the anode cylinder, an anode vacuum container including a metal container disposed to cover an upper surface of the magnetic piece, a cathode disposed along a central axis of the vacuum container, and an antenna externally discharging microwaves. The magnetic piece and the metal container are placed, in that order, on a shelf formed inwardly on a thin end section projecting from the open end section of the anode cylinder. When tightly welding the thin end section, a predetermined number of projections, projecting inwardly from the thin end section of the anode cylinder, loosely secure an outer perimeter bend of the metal container. The metal container is then accurately tightly welded to the anode cylinder without the metal container shifting off-center.

A ring-shaped depressed groove 11 is formed between a joining surface 10 of a stem insulating material 6 with a tubular metal container 16 and a joining surface 9 with cathode leads 2a and 2b. A metallized layer 8, formed at joining surface 9 and joining surface 10, is separated from edges 12 and 13 of ring-shaped depressed groove 11. The resulting magnetron reliably prevents discharges generated between the joining surface of the stem insulating material, with the tubular metal container, and the joining surface, with the cathode leads.

An image forming apparatus includes an image forming portion; a supplying device for supplying a toner; a transfer device capable of transferring the toner image from the image forming portion onto a toner image receiving member; a first detecting portion for detecting a transfer current of the transfer device; a second detecting portion for detecting information on a toner amount of the transferred toner image; and a controller for controlling, during non-image formation, a supplying operation of the supplying device on the basis of a detection result of the first detecting portion when a toner image for measurement formed at the image forming portion is transferred by the transfer device at a transfer voltage lower than a discharge start voltage and on the basis of a detection result when the toner image for measurement transferred on the toner image receiving member is detected by the second detection portion.

An image forming apparatus includes a image bearing member (drum); a developing device for forming a developing portion at which an electrostatic latent image formed on the drum is developed with toner; a toner supply device for supplying toner to the developing device; a density detecting portion for detecting a density of a control toner image formed on the drum; a toner ratio detecting portion for detecting a toner ratio in a two component developer contained in the developing device; a transfer member for forming a transfer portion; a charging member for electrically charging the toner image formed by the developing device by being supplied with a bias of an identical polarity to a charge polarity of the toner; an adjusting portion for adjusting an amount of the toner supplied from the toner supply device so that the toner ratio is below a preset lower limit when the toner ratio detected by the toner ratio detecting portion reaches the lower limit; and a bias determining portion for determining, after the adjustment by the adjusting device, a condition of a bias to be applied to the charging member on the basis of a detection result of the density detecting portion with respect to the density of the control toner image formed on the drum.
摘要:
A magnetron including a tubular metallic container which is air-tightly connected to an anode, cathode leads for supporting a cathode with filaments being disposed in a central axial portion of the anode, a stem insulator formed with through holes through which the cathode leads pass, and external terminals formed with planar portions which are air-tightly connected to a surface of the stem insulator opposite to a surface facing the tubular metallic container and with connecting portions which are air-tightly connected to the cathode leads. The connecting portions are arranged to be bent in an axial direction of the cathode leads. It is possible to exhibit the effect of preventing vacuum break from occurring by oxidation or the like since the increase in the area of the connecting portions will result in elongation of the distance between the end portions of the connecting portions and the through holes.

摘要:
As a fuel oil additive, an ethylenic copolymer is provided which is derived from:(a) ethylene, and(b) at least one monomer selected from the group consisting of vinyl esters of saturated carboxylic acids, ethylenically unsaturated mono- or di-carboxylic acids and esters thereof which are represented by the general formula: ##STR1## wherein R.sup.1 represents hydrogen or a methyl group, R.sup.2 represents the group --OCOR.sup.4 or --COOR.sup.4 in which R.sup.4 represents hydrogen or an alkyl group having 1 to 18 carbon atoms, and R.sup.3 represents hydrogen or the group --COOR.sup.4 in which R.sup.4 has the same significance as above, having a number average molecular weight of less than 1,000 and a (b) component content of 1 to 25 mol %, and containing 2 to 10 alkyl branches per 100 methylene groups. Addition of the copolymer to a fuel oil provides a modified fuel oil having improved plugging resistance and having improved flowability.
