  • Publication number: 20190004465
    Abstract: An image forming apparatus includes: an image carrier that carries an image; a transport-path forming part that forms a transport path for developer used to develop the image carried by the image carrier; a transport member that transports the developer in the transport path; and a concentration detector that detects toner concentration in the developer in the transport path. The transport path includes a first portion and a second portion. Difference in sectional area between the second portion and the transport member in a direction intersecting a direction in which the developer is transported is smaller than difference in sectional area between the first portion and the transport member. The second portion is located downstream of the first portion in the direction in which the developer is transported. The concentration detector is disposed in the second position of the transport path.

  • Patent number: 9109276
    Abstract: A cylindrical internal surface processing method comprises forming a cylinder bore, roughening an upper section of the bore, depositing coating onto the bore, and machining a lower section of the bore and the coating. The forming of the cylinder bore includes forming the upper and lower sections with the lower section being axially spaced from the upper section and having an axial length greater than zero. The roughening creates a roughened surface such that a radially innermost edge of the roughened surface has an internal diameter smaller than an internal diameter of the lower section. The coating is deposited to cover the upper section and at least a portion of the lower section. The machining forms a tapered portion and a cylindrical portion, a radially outermost edge of the cylindrical portion having an internal diameter larger than that of a radially outermost edge of the roughened surface.
