Abstract: An image forming apparatus includes a photosensitive drum, a charging member, a developing member, a transfer member, first and second gears, a drive source, and a control unit. The charging member contacts the photosensitive drum and forms a charging portion to charge a surface of the photosensitive drum. The control unit performs control in such a manner that an image forming operation of performing image formation by rotating the photosensitive drum at a first rotational speed is executable. Where the control unit executes the image forming operation, the control unit performs a switch operation of stopping the photosensitive drum in a state in which the photosensitive drum is driven, while a non-image forming operation to be executed after the image forming operation is executed, and rotationally driving the photosensitive drum again at a second rotational speed faster than the first rotational speed, a plurality of times.

Abstract: According to one embodiment, an automatic analyzing apparatus includes a liquid tank, a first pump, a dispensing probe, and a thermal exchanger. The liquid tank stores a first liquid. The first pump pressurizes and sends the first liquid supplied from the liquid tank. The dispensing probe uses the first liquid that is sent out from the first pump as a pressure transmitting medium. The thermal exchanger exchanges heat between an atmosphere in the automatic analyzing apparatus and the first liquid in at least a part of a first flow path connecting the first pump to the liquid tank.

Abstract: An alkaline detergent for an automatic analyzer is disclosed, which is consisted of an alkaline solution containing polyoxyalkylene alkylether as a nonionic surfactant, and a cloud point-adjusting organic solvent.

Abstract: An example of the present invention is an automated biochemical analyzer which executes a process of analyzing a sample to be tested. The analyzer includes, an electrolyte detection unit which measures ions in the sample, a constant temperature bath which holds a solution mixture of the sample and the reagent at a predetermined measurement temperature, a cleaning unit which executes a cleaning process of cleaning at least one of parts used in a process of analyzing the sample, an analysis unit which executes an analysis process on at least one liquid of an additive to be added to the constant temperature bath, a cleaning solution to be used in the cleaning process, and an electrolytic solution to be used in the electrolyte detection unit, and acquires an index for representing properties, and a control unit which determines whether the index falls within a preset appropriate range.

Abstract: A specimen is sequentially sampled by a probe, and at least one of the number of times of cleaning and a cleaning time when cleaning the probe is changed based on at least one of the number of times of sampling of the specimen by the probe and a sampling amount of the specimen.
