摘要： A developing device including a housing, toner a developing roller, and a feed roller in pressure contact with the developing roller so as to form a nip portion and which feeds toner to the developing roller. The developing device including a feed stabilizing member contacting a lower portion of the feed roller so as to form a second nip portion and restricting toner feed quantity. The feed stabilizing member extending from a generally triangular-shaped first region below the first nip portion up to one side of the nip portion opposite to the first region side. The developing device further including a toner circulation path for pushing back toner from the first region through below the feed stabilizing member to a second region on the one side opposite to the first region side with an aid of pressure of toner that tends to accumulate in the first region.

摘要： A developing device having a plurality of toner carrying members for carrying toner on their outer peripheral surfaces, the plurality of toner carrying members being placed along a rotating direction of an image carrying member and out of contact with the image carrying member; and a developer carrying member for carrying a developer composed of toner and carriers and for supplying the toner to the plurality of toner carrying members. In the developing device, AC bias voltages are applied to the toner carrying members so as to cause the toner carried by the toner carrying members to stick to an electrostatic latent image formed on the image carrying member by the effect of electric fields induced by a voltage of the electrostatic latent image and the AC bias voltages applied to the toner carrying members. The amount of developing toner sticking on the image carrying member immediately after the image carrying member has passed a development area in an upstream side in the rotating direction of the image carrying member is larger than the amount of developing toner sticking on the image carrying member immediately after the image carrying member has passed a development area in a downstream side in the rotating direction of the image carrying member.

摘要： A developing device has a first toner carrier which carries, on an outer peripheral surface, toner to be fed to an electrostatic latent image formed on an image carrier and which is arranged out of contact with the image carrier; a second toner carrier which carries, on an outer peripheral surface, toner to be fed to the electrostatic latent image and which is arranged out of contact with the image carrier; and a developer carrier which carries a developer made up of toner and carriers and which feeds the toner to the first toner carrier and the second toner carrier. The toner carried by each of the first toner carrier and the second toner carrier is caused to adhere to the electrostatic latent image formed on the image carrier by application of an AC bias voltage to each of the first toner carrier and the second toner carrier.

摘要： Volume data are collected by swing scanning in which frames in different field angle settings are mixed by a wide scan set at a wide field angle to image a diagnostic target and an index part for recognizing the position of the diagnostic target and by a narrow scan set at a field angle θ2 narrower than the field angle in the wide scan to image the diagnostic target with high time resolution. Then, the wide ultrasonic image is used to set spatial coordinates based on the index part. The spatial coordinates are used to align the narrow ultrasonic image. While this positional relation is being maintained, the wide ultrasonic image, the narrow ultrasonic image and a given ultrasonic image are displayed in a predetermined form.

摘要： An ultrasound diagnosis apparatus and a 3-D image data scan method that can continuously display 3-D image data in both a pre-scan mode and a triggered entire volume mode by collecting the volume data of a plurality of volume scan regions of an object from the start of the scan. In the pre-scan mode, a plurality of 3-D sub-regions are set by dividing an object scan region along a direction vertical to the reference scan plane. In a triggered volume mode for collecting volume data, a 3-D scan of a 3-D sub-region including the reference scan plane is performed in preference to other 3-D sub-regions in order to continuously display 2-D image data acquired on the reference scan plane in the pre-scan mode and MPR image data acquired in the entire triggered volume mode from an initial scan time.
