摘要： A controller of an image forming device is configured to perform: an elapsed time acquisition process; an evaluation value acquisition process; and an outputting process. The elapsed time acquisition process acquires a length of elapsed time in each of a first time period and a second time period. The evaluation value acquisition process acquires a first evaluation value for the first time period and a second evaluation value for the second time period. Each of the first and second evaluation values specifies a degree of change in a quality of colorant in a cartridge during a corresponding one of the first and second time periods and is based on the length of elapsed time acquired in the elapsed time acquisition process and an ambient environment of the cartridge affecting the quality of the colorant. The outputting process outputs an output value reflecting both the first and second evaluation values.

摘要： A developing device includes a tubular member through which developer is to be transported, an end support that supports an end of the tubular member, and a blocking member that extends over an end face of the tubular member and the end support and that blocks the developer from entering a gap between an outer peripheral surface of the tubular member and the end support.

摘要： A cartridge (B1) is mountable to an apparatus main assembly (A1) of an image forming apparatus, the apparatus main assembly (A1) having mounted a photosensitive drum (10) separate from the cartridge (B1). The cartridge (B1) comprising: a developing roller (13) including an elastic layer (13d) for bearing developer (t), wherein the elastic layer (13d) can be pressured against the photosensitive drum (10); a frame (16, 34, 36, 46) supporting the developing roller (13); a drive input member (180, 280) configured to receive input of a rotational force to rotate the developing roller (13); a movable part (70) movably supported by the frame (16, 34, 36, 46) and movable to a first position and to a second position relative to the frame (16, 34, 36, 46); and an elastic part (71) provided between the frame (16, 34, 36, 46) and the movable part (70) to urge the movable part (70). The movable part (70) includes a first force receiving part (70a) configured to receive a first external force from the apparatus main assembly (A1), in a direction of moving from the first position to the second position, and a second force receiving part (70g, 170g) configured to receive a second external force from the apparatus main assembly (A1), in a direction of moving from the second position to the first position. When the movable part (70) receives the first external force from the apparatus main assembly (A1) at the first force receiving part (70a) and is at the second position, the movable part (70) receives an urging force (F 10) from the elastic part (71) in a direction of moving the movable part (70) from the second position to the first position. The first force receiving part (70a) is configured to receive the first external force from the apparatus main assembly (A1) so that, in a state that the cartridge (B1) is mounted on the apparatus main assembly (A1), the movable part (70) is at the second position and the elastic layer (13d) is pressured against the photosensitive drum (10) via the elastic part (71) and the frame (16, 34, 36, 46). The second force receiving part (70g, 170g) is configured to receive the second external force from the apparatus main assembly (A1) so that, in a state that the cartridge (B1) is mounted on the apparatus main assembly (A1), the movable part (70) is at the first position and the elastic layer (13d) is spaced from the photosensitive drum (10).
