摘要： An electrophotographic image forming apparatus for forming an image on a recording material includes an electrophotographic photosensitive drum, a charger for charging the photosensitive drum, a developer for developing a latent image formed on the photosensitive drum into a toner image, a transferrer for transferring the toner image onto the recording material, a fixer for fixing the toner image on the recording material, a motor, a main assembly side gear for receiving a driving force from the motor, and a hole formed substantially at a center of the gear. The hole has a polygonal cross-section. The apparatus also includes a projection provided at a longitudinal end of the photosensitive drum. When the main assembly side gear rotates with the hole and projection engaged with each other, a rotational driving force is transmitted from the gear to the photosensitive drum through the hole and the projection with the projection is pulled into the hole. An end portion of a shaft having the projection and a surface defining the hole contact each other so that the process cartridge is positioned in place in a longitudinal direction of the photosensitive drum relative to the main assembly. The apparatus also includes a mover for imparting relative movement between the hole and the photosensitive drum to engage the projection with the hole.

摘要： Disclosed are a lactone-modified polyvinyl alcohol and a process for the preparation thereof, a polymer composition, a permanently anti-electrostatic resin composition, a lactone-modified resin having hydroxyl groups, and a process for the preparation thereof. The lactone-modified polyvinyl alcohol can be used in wide fields owing to the capability of freely adjusting the water solubility, such as water-soluble, gradually water-soluble, low water-soluble, and water-insoluble by a degree modified by lactone compounds, and owing to possessing properties both of PVA and lactones. Furthermore, the lactone-modified polyvinyl alcohol has properties such as being plasticizers or softening agents, and as a result, there can be provided a polymer composition having excellent properties by mixing with a hydrophilic polymer or polar polymer. Still further, a blend resin composition in which a variety of resins are blended with the lactone-modified polyvinyl alcohol has an excellent permanently-anti-electrostatic property, and the resin composition having a permanently-anti-electrostatic property can be preferably employed as a variety of molded articles such as parts for electric appliances, textiles, films, etc.
