A developer collection container includes a developer storing portion having first and second end portions in a longitudinal direction thereof. A developer supply opening is provided on the first end portion through which the developer is supplied into the developer storing portion. A rotation member is rotatably provided so as to extend substantially from the first end portion to the second end portion. The rotation member rotates so as to convey the developer in the longitudinal direction of the developer storing portion. In a first region closer to the first end portion, the rotation member conveys the developer in a direction from the first end portion toward the second end portion with a conveying power which is larger than a conveying power with which the rotation member conveys the developer in a second region closer to the second end portion.

An electronic still camera includes a finder optical system for viewing a subject image. An imaging section obtains the subject image. A display section displays the subject image based on image data associated with the subject image obtained by the imaging section. A mode selecting section selects either a first mode in which the electronic still camera performs imaging operation using the imaging section while a user views the subject image through the finder optical system or a second mode in which the electronic still camera performs imaging operation using the imaging section while the user views the subject image on the display section. A first focus detection circuit performs a first focus detecting operation when the first mode is selected by the mode selecting section. A second focus detection circuit performs a second focus detecting operation when the second mode is selected by the mode selecting section.

The present invention provides a plated article that has a thin seed layer having uniform thickness, formed by electroless plating and allowing formation of ultrafine wiring, and that avoids the complicated formation of a bilayer of a barrier layer and a catalytic metal layer prior to forming the seed layer. The present invention also provides a method for manufacturing the plated article. The plated article has an alloy thin film formed on a substrate and having a catalytically active metal (A) for electroless plating and a metal (B) capable of undergoing displacement plating with a metal ion contained in an electroless plating solution, and a metal thin film formed on the alloy thin film by electroless displacement and reduction plating. The alloy thin film of the catalytically active metal (A) and the metal (B) capable of displacement plating has a composition comprising 5 at % to 40 at % of the metal (A). The metal thin film formed by electroless displacement and reduction plating is a metal thin film having a thickness no greater than 10 nm and a resistivity no greater than 10 μΩ·cm. Preferably, the metal (B) has a barrier function with respect to a metal of the metal thin film.

The present invention realizes efficient dust removal in an optical apparatus in such a manner that a single circuit drives a plurality of dust reduction optical elements to vibrate. When the optical elements have different resonance frequencies, it can be configured such that the vibration exciting frequency can be changed in a range including the resonance frequencies of all the optical elements. In this case, the optical element driven can also be switched according to the change in frequency so that only the optical element having a resonance frequency close to the driving frequency will be driven. Alternatively, it can be configured such that the driving time or applied voltage can be changed according to the characteristics of the optical element driven.

An image forming apparatus includes an image forming unit having an image carrier, a developing agent container for holding a developing agent, and a developing agent supplier for supplying the developing agent from the developing agent container to the image carrier. A controller determines the amount of use of the image forming unit. A shaking mechanism shakes the image forming unit from time to time, at intervals determined by the controller according to the amount of use of the image forming unit. The shaking loosens the developing agent so as to maintain its fluidity, thereby avoiding faint image formation.

An image-forming apparatus includes a mechanism that controls the replenishment amount of toner to a predetermined value. A toner cartridge holds toner therein. The toner cartridge is detachably attached to a process cartridge. The process cartridge has a toner reservoir that holds the toner supplied from the toner cartridge, a photoconductive drum and a developing roller that supplies the toner to the photoconductive drum. A valve is located between the toner cartridge and the process cartridge and supplies the toner from the toner cartridge to the process cartridge. When the valve rotates, the valve supplies a volume of toner in such a way that the toner in the toner reservoir fills a volume not more than a predetermined fraction of a maximum capacity of the toner reservoir.

An electronic image pickup apparatus comprises a photographic optical system; solid state image pickup devices disposed on a plant where a subject image formed by subject beams which have passed through the photographic optical system is formed; a main mirror disposed between the photographic optical system and the solid state image pickup devices, wherein a part of the main mirror is formed of a half mirror to divide the subject beams which have passed through the photographic optical system into an observing beam and a focus detecting beam; a sub-mirror for reflecting the subject beam which has passed through the part of the main mirror; a focus detecting optical system for forming an image of the subject beam reflected by the sub-mirror on a partial area of the solid image pickup devices; and an electrical circuit for outputting focus detecting information based on image signals of the partial areas of the solid image pickup devices. The structure provides an electronic image pickup apparatus which contributes to the down-sizing of the apparatus and to the reduction of production cost by eliminating an image pickup device which is dedicated for focus detection.
