摘要： A developer includes a waste toner container having a cleaning member to clean a photoconductive drum, and a waste toner transporting member to transport waste toner from the photoconductive drum to a waste toner storage area. The waste toner transporting member is moved up, down, forward, and backward by a rotation member having an eccentricity unit. As the rotation member rotates, the waste toner transporting member, which is connected to the eccentricity unit, moves up, down, forward, and backward.

摘要： A developing device has a housing including a toner container containing toner, and a developing unit. The developing unit includes a developing roller and a photoconductive drum, and a barrier member including a toner supply window. The barrier member is combined with the housing to separate the toner container and the developing unit from each other. The developing unit also includes a blocking film that is attached to the barrier member to block the toner supply window. An end of the blocking film is exposed outside the housing through an opening formed in a sidewall of the housing. A bottom surface and first and second side surfaces of the barrier member are attached to a bottom surface and first and second side surfaces of the housing by using a welding process, and a distance between the first and second side surfaces of the barrier member and a distance between the first and second side surfaces of the housing increase from bottom to top.

摘要： A developing unit includes a waste toner housing having an upper housing and a lower housing which face each other, at least one support unit to allow connection between the upper and lower housings, and to support facing surfaces of the upper and lower housings, and a toner housing which is disposed on a lower part of the waste toner housing and is spaced apart from the waste toner housing at a predetermined distance. Accordingly, the waste toner housing is prevented from being deformed by heat and pressure, and thus white lines on images, flowback of waste toner and insufficient cleaning, which are caused by interference with the light path due to deformation of the waste toner housing, can be reduced. Additionally, tolerance can be greatly reduced as a result of resolving the problem of deformation of the waste toner housing, so a developing unit having a smaller size can be provided.

摘要： A method and apparatus for detecting a free page of a memory device, and a method and apparatus for decoding an error correction code by using the method and apparatus for detecting a free page are provided. Free page data read from the memory is converted into a converted codeword for inclusion as an element of an error correction code field. The converted codeword is compared to an initially set target codeword to detect an amount of non-identical bits. A page read from the memory is determined to be a free page when the amount of non-identical bits is equal to or less than an initially set threshold value.
