A printer apparatus including a printing-medium conveying unit conveying a printing medium, a sheet conveying unit conveying a thermal transfer sheet having an image protecting layer to be thermally transferred onto an image formed on the printing medium, a thermal head with heating elements linearly arranged in a direction orthogonal to a conveyance direction of the printing medium, and a control unit driving and controlling the thermal head. For selectively applying different amounts of thermal energy to the heating elements to form an uneven pattern on the image protecting layer thermally transferred onto the image on the printing medium, the control unit randomly divides a row of the heating elements into heating element groups each including at least two adjacent heating elements, applies the same amount of thermal energy to heating elements in the same heating element group, and applies different amounts of thermal energy to adjacent heating element groups.

An image forming apparatus of the present invention includes a movable body to be charged and a charger including a charging member that contacts or adjoins the body to be charged and applies a voltage, including an AC component, to the charging member for thereby charging the body. A protection substance for protecting the surface of the body from deterioration ascribable to charging is caused to exist on the body. The number of particular elements, contained in the protection substance and detected by an X-ray photon spectral analyzer (XPS) in a zone where the charging member charges the body, is held in a particular ratio to the total number of all elements constituting the outermost surface of the body and also detected by the XPS.

A non-aqueous electrolyte secondary battery includes a positive electrode 11 made of graphite powder and a negative electrode 13 made of lithium metal or a lithium-intercalatable/deintercalatable material. The positive electrode 11 and the negative electrode 13 are faced to each other with an electrolyte, containing a lithium salt, interposed in between. The positive electrode 11 has a carbon-derived absorption peak which appears within a range of 3200 gauss to 3400 gauss in an electron spin resonance method in which measurement is performed using an X band. A relative ratio (ΔH40K/ΔH296K) of the full width of half maximum intensity ΔH40K of the peak measured at a temperature of 40 K to the full width of half maximum intensity ΔH296K of the peak measured at a temperature of 296 K is 2.1 or more. Accordingly, it is possible to provide the non-aqueous electrolyte secondary battery which prevents degradation of the capacity in charge/discharge cycles after performing high temperature floating charge.

A screw and a screwdriver of the present invention provide an easy insertion of screwdriver bits and the screwdriver conveys a large torque when fastening so that the screwdriver does not rise up from the screw and does not damage recesses to fasten and loosen the screw. The screw has a high strength structure for shear force. A plurality of recesses for the insertion of the bits of the screwdriver are disposed on a top face of a screw head of the screw. Engaging walls are disposed to engage with the bits between the recesses. The whole shape of the recesses has a tapered cross section. Vertical engaging faces are formed inside the recesses near an outer circumference in a fastening direction of the screw and extend to a thickness direction of the screw head. The vertical engaging faces are parallel to bisectors of the width of the engaging walls through a central axis. The screwdriver has the bits having the same shape as the recesses of the screw head with respect to the central axis. The bits have vertical engaging drive faces to engage with the vertical engaging faces.
