<P>PROBLEM TO BE SOLVED: To provide an image forming unit and an image forming device which can obtain sufficient image density. <P>SOLUTION: A process unit 11 as an image forming unit includes: a photosensitive drum 14; a developing roller 16 for supplying a developer to the photosensitive drum 14; first and second supplying rollers 17 and 18, respectively, for supplying the developer to the developing roller 16; and a transfer belt unit for carrying a recording medium along a predetermined carrying surface CP so that the recording medium contacts with the photosensitive drum 14. The first supplying roller 17 is disposed on the side closer to the carrying surface CP in a direction orthogonal to the carrying surface CP, as compared with the second supplying roller 18. The supplying rollers 17 and 18 are disposed so as to make a tangent line A of a circumference of the first supplying roller 17 on a side separated from the developing roller 16 in the direction orthogonal to the carrying surface CP have a longer distance from the developing roller 16 within a surface parallel with the carrying surface CP, than a tangent line B of a circumference of the second carrying roller 18 on a side separated from the developing roller 16 in the same direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
