摘要： An image formation apparatus includes an image carrier and a toner carrier having a concave portion arrayed in a regular pattern on its surface. A latent image that is carried on the image carrier is developed by toner carried in the concave portion by applying a development voltage to the toner carrier. After the toner carrier has developed the latent image, at least one layer of toner remains in the concave portion.

摘要： A developing device includes a rotatable toner bearing roller and a regulation blade. The toner bearing roller has regularly-arranged projecting sections and non-projecting sections, bears toner whose volume average particle diameter is smaller than a depth of the non-projecting section relative to the projecting section, and develops a latent image borne on an image bearing member with the toner borne on the toner bearing roller. The regulation blade is for regulating an amount of the toner borne on the toner bearing roller, and abuts, with a predetermined width, against a circumferential surface of the toner bearing roller in a circumferential direction thereof in such a manner that a longitudinal direction of the regulation blade is along a direction of a rotation axis of the toner bearing roller. A tip edge of the regulation blade in a lateral direction and a thickness direction thereof is located within an abutting section having the predetermined width. The predetermined width is larger than a maximum width, in the circumferential direction, of the non-projecting section.

摘要： A developer carrier has concave portions regularly arranged on the surface thereof and being rotatable with a developer thereon. A contact member is made of an elastic rubber material, is in contact with the surface of the developer carrier, and vibrates with the rotation of the developer carrier. A value obtained by dividing a movement speed of the surface at the time of rotation of the developer carrier by a pitch of the concave portions in a peripheral direction of the developer carrier is smaller than a peak vibrational frequency of the contact member when a loss tangent obtained by dividing a loss elastic modulus of the contact member by a storage elastic modulus is the greatest.

摘要： By a QTL analysis and so forth using 4-HPPD inhibitor-susceptible rice and 4-HPPD inhibitor-resistant rice, a hypothetical gene (HIS1 gene) of an iron/ascorbate-dependent oxidoreductase gene located on a short arm of chromosome 2 of rice has been identified as a 4-HPPD inhibitor-resistance gene. Further, it has also been revealed that a homologous gene (HSL1 gene) of the HIS1 gene is located on chromosome 6 of rice. Furthermore, it has been found out that utilizations of these genes make it possible to efficiently produce a plant having increased resistance or susceptibility to a 4-HPPD inhibitor and to efficiently determine whether a plant has resistance or susceptibility to a 4-HPPD inhibitor.
