Abstract: An electrophotographic photoconductor is provided that includes a conductive substrate, an undercoat layer overlying the conductive substrate, and a photosensitive layer overlying the undercoat layer. The undercoat layer contains zinc oxide particles and a binder resin and has a volume resistivity of 0.03×106 ?·cm or less in an electrical field of 5 V/?m at a temperature of 23 degrees C. and a relative humidity of 55%. The photosensitive layer contains a compound represented by the following general formula (1): where each of R1 to R3 independently represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 6 carbon atoms which may have a substituent, or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms.

Abstract: A sheet feeding device (4) includes a placing plate (34) on which a sheet is placed; a pickup roller (71) which feeds the sheet to a conveying path (25); a lift member (36) which is turned around a rotating shaft (46) to elevate the placing plate (34) and to make an downstream side end portion of an uppermost sheet in a conveying direction come into contact with the pickup roller (71); a drive unit (37) which rotates the rotating shaft (46); a variable resistor (54) which changes an electric resistance value depending on a rotating angle of the rotating shaft (46); and a control part (77) which calculates the rotating angle of the rotating shaft (46) using the electric resistance value measured by the variable resistor (54) and detects an amount of the sheets based on the calculated rotating angle.

Abstract: A cooling device includes a fan main body, a first housing, a second housing, a drive portion, and a rotation control portion. The second housing is configured to be rotatable between a predetermined first rotation position P1 and a second rotation position P2 reached through a rotation by a predetermined angle about a shaft from the first rotation position P1. The rotation control portion controls the drive portion to move the second housing to the first rotation position P1 or the second rotation position P2.

Abstract: An image forming apparatus of the present disclosure is provided with an apparatus main body, a caster, and a cover member. The caster movably supports the apparatus main body. The cover member is mounted to a side surface of the apparatus main body. The caster includes a wheel and a main body portion that swivelably supports a rotation shaft of the wheel. A nut portion is provided integrally with an upper part of the main body portion. A swiveling restriction portion that restricts swiveling of the nut portion is formed integrally with the cover member.

Abstract: An alcoholic beverage is provided which contains 0.01 to 5 parts of a chelate compound by weight for improvement of the aroma and taste of the beverage and for derivation of enzymes to produce a detoxifying effect on carcinogenic substances and undesirable bacteria and viruses, and an antioxidative effect for reducing active oxygen in living bodies.

Abstract: The present invention discloses, a bispecific monoclonal antibody to an ansamitocin derivative and a target antigen, particularly tumor-associated antigen, which can carry an ansamitocin derivative in a stable and inactive form at other sites than the target and release the active-form ansamitocin derivative at the target site, so that an anticancer agent having excellent durability and selectivity with little adverse action can be prepared using the bispecific monoclonal antibody and ansamitocin derivatives.
