摘要： The tester and the test method for testing an eccentricity of a head turnout zone of a magnetic disk determine a turnout zone as acceptable or unacceptable by spirally scanning a turnout zone of a magnetic disk with a laser spot by rotating the magnetic disk and continuously moving either the laser spot radially of the magnetic disk or the magnetic disk radially thereof, obtaining a detection signal having amplitude corresponding to an intensity of a scattering light from the magnetic disk irradiated with the laser spot, extracting a first waveform of the detection signal corresponding to an intermediate region between an inside variation region in which an inside boarder line of the turnout zone radially of the magnetic disk by radial movement of the turnout zone caused by an ecentricity of the turnout zone and an outside variation region in which an outside boarder line of the turnout zone radially of the magnetic disk by the radial movement of the turnout zone caused by the eccentricity of the magnetic disk and a second waveform of either the detection signal adjacent to the first waveform and corresponding to the inside variation region or the detection signal adjacent to the first waveform and corresponding to the outside variation region and detecting an eccntricity of the turnout zone on a basis of a positional relation between the first and second waveforms.

摘要： A detection mechanism is provided with a sealing member made of elastic material for preventing toner leakage between (a) a pierced wall surface of a toner tank through which a rotating shaft is inserted and (b) a second side plate provided on the rotating shaft. With this structure, a flat splicing surface of the sealing member is made to closely contact a second side plate that can be coated with a high lubricant member whose frictional forces is small. When a sealing force of the sealing member is strongly compressed, the sealing member prevents toner from coming into the sliding surface.

摘要： A developer cartridge for image forming apparatuses which performs development to form images with non-magnetic, one-component type developer. The cartridge includes a developing roller for supplying developer to a photoconductor drum, a developer feed roller in non-contact with the developing roller for supply developer to the developing roller, and a developer-layer thickness control member for controlling the thickness of the developer layer on the developing roller. The developer feed roller is shaped as a regular polygonal prism. Since no recesses are formed in the surface of the regular polygonal prism, driving torque does not increase when developer is scrubbed from the prism, thus ensuring consistent operation and improved image quality. Non-magnetic, one-component type developer is compressed onto the developing roller by supplying the developer via the developer feed roller into a bottleneck between the developing roller and a developer applying member. The amount of developer which passes through the bottleneck onto the developing roller is controlled by a temporary reservoir, the pressurization thereof ensuring application of the developer to the developing roller. A control roller may be used against the developing roller to lower friction of developer, thereby preventing deposition of developer on the control roller while establishing a consistent amount of developer on the developing roller.

摘要翻译： 用于图像形成装置的显影剂盒，其用非磁性单组分型显影剂进行显影以形成图像。 盒包括用于将显影剂供应到感光鼓的显影辊，与用于向显影辊供应显影剂的显影辊非接触的显影剂供给辊以及用于控制显影剂层厚度的显影剂层厚度控制部件 在显影辊上。 显影剂供给辊的形状为正多边形棱镜。 由于在正多边形棱镜的表面没有形成凹部，所以当从棱镜上洗涤显影剂时，驱动扭矩不会增加，从而确保一致的操作和改进的图像质量。 通过将显影剂通过显影剂供给辊供给到显影辊和显影剂施加构件之间的瓶颈中，非磁性的单组分型显影剂被压缩到显影辊上。 通过瓶颈到显影辊上的显影剂的量由临时储存器控制，其加压确保将显影剂施加到显影辊上。 可以使用控制辊抵靠显影辊以降低显影剂的摩擦，从而防止显影剂在控制辊上沉积，同时在显影辊上建立一致量的显影剂。
