摘要:
A cleaning element is arranged on the backside of the toner layer metering blade, i.e., the side opposite to the surface in contact with the developer support, in order to prevent the cleaning element from damaging the blade surface and the abutment surface of the metering blade against the developer support. This cleaning element is frictionally moved across the backside of the toner layer metering blade to remove stuck toner from the toner layer metering blade or prevent occurrence of buildups.

A developing apparatus capable of supplying a uniform thin layer of toner and of preventing toner scattering and leakage is provided, where the developing apparatus includes a supply roller for supplying toner to an outer peripheral surface of a toner carrier, the toner carrier for transferring the supplied toner by rotation and a layer thickness controlling member for controlling a thickness of the layer of the supplied toner at a predetermined value while making slide contact with the outer peripheral surface of the toner carrier via the toner, wherein the thin toner layer is supplied to an electrostatic latent image on an image carrier. The layer thickness controlling member is formed of an elastic plate to have a bent portion convex toward the toner carrier. The layer thickness controlling member is held by sealing members so that the bent portion makes elastic contact with the toner carrier outer peripheral surface over a nearly entire length of the toner carrier.

The image forming portion of this image forming apparatus includes a LSU, a photosensitive drum, a developing unit holder, a multiple number of developing units, an intermediate transfer element, a transfer element and a fixing unit. All the developing units are of an identical configuration. Therefore, for replacement of developing units, the operator may and should remove any color of developing unit in the same fashion and attach a fresh developing unit of the color in the same fashion. The image forming portion sets up the image forming conditions for individual colors in the developing order.

An object of the invention is to make an exact judgment on suitability of a replaceable component such as a toner supplying container with use of an existing mechanism of an image forming apparatus, without additionally providing a data storage component designed for a consumable product which is detachably attached to the apparatus, or a data reading component to be placed in the image forming apparatus main body. In an incorporated control section, a specific part of a replaceable component, which is placed on an original platform prior to being loaded into the apparatus, is optically scanned to read image information, and, based on the reading result, whether or not the replaceable component is suitable for the image forming apparatus is judged.

A stator includes a stator core formed from a plurality of split cores arranged in a circumferential direction, and a cylindrical body that surrounds the stator core from a periphery and secures the stator core. The split cores each have a first end portion on one end in the circumferential direction, and a second end portion on the other end in the circumferential direction. The first end portion has a protruding portion that protrudes outward in the circumferential direction, and the second end portion has a depressed portion that is depressed inward in the circumferential direction and fits together with the protruding portion of the first end portion of an adjacent split core.

A device includes: a storage storing second logical expressions; an storage storing an essential condition which indicates a set of one or more second logical expressions selected such that a proposition is not satisfied that the post-condition is satisfied immediately after a program is executed when a logical product of other second logical expressions obtained by excluding the set indicated by the essential condition from the storage is satisfied; a generator generating a candidate condition represented by a logical product of one or more second logical expressions to include a common second logical expression with the set indicated by the essential condition; a judging unit judging whether satisfied is a proposition that the post-condition is satisfied immediately after the program is executed when the candidate condition is satisfied, and an output unit configured to output the candidate condition determined to satisfy the proposition as representing a pre-condition of the program.

Provided is a manufacturing method that allows even a PDP having high-definition cells to exhibit excellent image display performance with reduced power consumption by effectively preventing impurities from adhering to the protective layer. Specifically, in a pre-baking step, a back substrate 9 is baked at a pre-baking temperature. Here, a highest pre-baking temperature is set to be lower than a softening point of a sealing material. The back substrate 9 is superposed on a front substrate 2. Then, a sealing step is performed in a sealing atmosphere prepared by mixing a predetermined amount of a reducing gas with a non-oxidizing gas. The above enables the impurities attributed to organic components due to a sealing material paste to remain as low molecular components, whereby the impurities are evacuated and removed in an evacuating step performed after the sealing step. This prevents adherence of the impurities to the protective layer 8.

The present invention provides a method of manufacturing a blue silicate phosphor having high luminance and a chromaticity y comparable to or lower than that of BAM:Eu. The present invention is a method of manufacturing a blue silicate phosphor represented by the general formula aAO.bEuO.(Mg1−w,Znw)O.cSiO2.dCaCl2, where A is at least one selected from Sr, Ba and Ca, and 2.970≦a≦3.500, 0.006≦b≦0.030, 1.900≦c≦2.100, 0≦d≦0.05, and 0≦w≦1 are satisfied. In this manufacturing method, heat treatment is carried out in a gas atmosphere having an oxygen partial pressure of 1×10−15.5 atm to 1×10−10 atm at a temperature of 1200° C. to 1400° C.
