    • A non-magnetic one-component developer comprises a binder resin and a colorant, and has a volume-average particle diameter (dv) in a range of 5-15 .mu.m, a ratio (dv/dn) of the volume-average particle diameter (dv) to the number-average particle diameter (dn) in a range of 1.00-1.40, a quotient (Sc/Sr) obtained by dividing the area (Sc) of a circle supposing the absolute maximum length of a particle is a diameter by the real projected area (Sr) of the particle in a range of 1.00-1.30, a product (AxdnxD) of the specific surface area (A) (m.sup.2 /g) as measured in accordance with the BET method, the number-average particle diameter (dn) (.mu.m) and the true specific gravity (D) in a range of 5-10, and a ratio (Q/A) of the charge level (Q) (.mu.c/g) to the specific surface area (A) in a range of 80-150. The developer is substantially spherical from both conditions of Sc/Sr and AxdnxD, and is suitable for use in a development process in which cleaning is conducted at the same time as development. A development process making use of the non-magnetic one-component developer is also disclosed.

    • A method of this invention is a non-overwritable method of recording information on a magnetooptical recording medium in which at least two layers including a first layer comprising a magnetic thin film having a perpendicular magnetic anisotropy, and a second layer comprising a magnetic thin film having a perpendicular magnetic anisotropy, and having a Curie temperature higher than or almost equal to a Curie temperature of the first layer are stacked to be exchange-coupled to each other, and a direction of magnetization of only the second layer can be aligned in a predetermined direction by a first external field at a room temperature while a direction of magnetization of the first layer is left unchanged. The medium which has already been set in a state wherein the direction of magnetization of the second layer is aligned in the predetermined direction, and a interface magnetic wall is formed between the first and second layers is prepared. A beam is radiated on the prepared medium while rotating the medium. The beam is pulse-modulated according to information to be recorded between a first intensity level for giving, to the medium, a temperature lower than the Curie temperature T.sub.C1 of the first layer, and higher than or equal to a lowest temperature T.sub.LS for causing the interface magnetic wall between the first and second layers to disappear, and a second intensity level for giving, to the medium, a temperature lower than the temperature T.sub.LS. In another aspect of this invention, the first intensity level is set at a level for giving, to the medium, a temperature equal to or higher than T.sub.C1 and lower than the Curie temperature T.sub.C2 of the second layer.

    • A sheet sorting apparatus with a stapler includes a plurality of bin trays which are arranged substantially vertically with predetermined clearances between adjacent bin trays, which are inclined to provide an inclined sheet receiving surfaces and which are independently movable substantially in the vertical direction, wherein the bin trays are so disposed that those ends of adjacent ones of the bin trays which are closer to the sheet inlet are deviated when seen in a direction substantially perpendicular to the sheet receiving surface; bin tray shifting device for moving the plurality of the bin trays stepwisely substantially in the vertical direction to oppose the respective bin trays to a sheet inlet of the sorting apparatus; stapling device, disposed substantially on an extension of the inclined sheet receiving surface and having a stapling head movable to above the sheet receiving surface and an anvil movable to below the sheet receiving surface, for stapling the sheets interposed between the stapling head and the anvil; and a second shifting device for shifting the bin tray immediately above the bin tray opposed to the stapling device in a direction increasing the deviation, wherein the stapling head is moved using a space provided by the deviation, and wherein the expanded clearance is smaller than a height of the stapling head.
