    摘要： The present invention relates to a process cartridge removably mountable on an image forming apparatus comprising a support, a rotary member having an image bearing surface and rotatably supported by the support, and a rotatable developing roller supported by the support, for carrying developer thereon and supplying the developer to the image bearing surface to develop a latent image formed on the image bearing surface. A first gear is arranged coaxial with the rotary member, a second gear is arranged coaxial with the developing roller and meshed with the first gear, and a guide means is provided for guiding the developing roller in a direction toward and away from the rotary member. The direction in which the developing roller is guided by the guide means is inclined with respect to a straight line connecting the center of rotation of the rotary member to the center of rotation of the developing roller, by an angle between 0.7.times..THETA. (.THETA. is a pressure angle of the second gear) and 1.3.times..THETA.. The cartridge further includes a bias means for biasing the developing roller toward the image bearing surface.

    摘要： A bearing mechanism includes a shaft for guiding a reciprocable carriage; a bearing mounted on the carriage and slidable relative to the shaft; a receiving member extending from the bearing to receive lubricant oil removed by the sliding movement between the shaft and the bearing; and a lubricant oil passage formed in the bearing to connect the receiving member and a portion between the shaft and the bearing.

    摘要： Disclosed is a method for producing at least one of an α,β-unsaturated aldehyde and an α,β-unsaturated carboxylic acid from an alcohol in a liquid phase through a simple process. Namely, at least one of an α,β-unsaturated aldehyde and an α,β-unsaturated carboxylic acid is produced by dehydrating and oxidizing an alcohol in a liquid phase at 110 to 250° C. in the presence of molecular oxygen and a noble metal-containing catalyst. Alternatively, at least one of an α,β-unsaturated aldehyde and an α,β-unsaturated carboxylic acid is produced by dehydrating and oxidizing an alcohol in a liquid phase in the presence of molecular oxygen, a noble metal-containing catalyst, and an acidic substance.
