摘要:
A non-volatile storage device comprises a non-volatile memory into which data is written per unit area, and a memory controller for controlling writing of data into the non-volatile memory. The memory controller comprises a first storage section for holding data input from the outside of the device, a first control section for writing data which is held by the first storage section and whose amount corresponds to the unit area, into the non-volatile memory in a unit area-by-unit area basis, and writing data which is held by the first storage section and whose amount is less than the unit area, into a second storage section, and a second control section for writing data held by the second storage section into the non-volatile memory.

An image forming apparatus includes a movable image bearing member, a charger means including a charge member for electrically charging the image bearing member with electroconductive particles between the charge member and the image bearing member and a developing member for developing a latent image with toner mixed with electroconductive particles. The latent image is formed on the image bearing member having been charged by the charging means, and a toner image provided by development of the latent image by the developing member is transferred onto a recording material. The electroconductive particles mixed in the toner is carried by the image bearing member and are fed to between the charge member and the image bearing member. The width A, measured in a direction perpendicular to a moving direction of the image bearing member, in which the electroconductive particle are present between the charge member and the image bearing member, a width B in which the developing means is capable of effecting development, and a recording width C of a maximum size recording material, satisfy: A>B≧C.
摘要:
A green sheet including a binder containing an acrylic resin having no polar group and a ceramics material in powder is prepared, and connection via are formed in the green sheet. Further, a conductor layer having virtually no voids is placed on the green sheet and a mask is also placed on the conductor layer. Then, the conductor layer is patterned by wet-etching so that wiring is formed thereon. A plurality of the green sheets thus formed are laminated, and a binding sheet, which contains an inorganic composition that has virtually no sintering shrinkage at the firing temperature of the multi-layered body as a main component, is formed on either both surfaces or one surface of the laminated body, and this is then fired, and thereafter, the binding sheet is removed.
