Abstract: A cartridge includes a housing, a drive-transmission member and a detected body. The housing has a first wall and a second wall opposing each other in a first direction from the second wall toward the first wall. The drive-transmission member is rotatable about a first axis parallel to the first direction for transmitting a drive force. The detected body is rotatable about a second axis parallel to the first axis upon receipt of the drive force to move the detected body irreversibly from a first position to a second position. The detected body includes: a detected portion; a receiving portion configured to receive the drive force; and a peripheral portion positioned downstream of the receiving portion in a radial direction of the detected body away from the second axis, at least a portion of the detected portion being positioned on the peripheral portion.

Abstract: A cartridge includes a housing having a first wall and a second wall opposing each other, a drive-transmission member and a detected body rotatable about a first axis and a second axis respectively parallel to a first direction from the second wall toward the first wall. The detected body having a detected portion is movable first in the first direction and then in a second direction opposite to the first direction relative to the first wall while irreversibly moving from a first position to a second position, a distance between the detected portion and the first wall in the first direction being longer at the second position than at the first position. The drive-transmission member includes a first engaging portion engageable with the detected body at the first position and positioned upstream of an abutment portion abuttable with a receiving portion of the detected body in the first direction.

Abstract: A developer cartridge includes: a first rotary body having at least one detected part; and a second rotary body. The first rotary body is configured to rotate between a first position, in which a transmission part is disposed opposite the second rotary body, and a second position, in which a non-transmission part is disposed opposite the second rotary body. The first rotary body includes a contacted part. A photosensitive body cartridge includes a moving member. When the moving member is in a third position, the moving member contacts the contacted part of the first rotary body disposed in the second position, causing the first rotary body to rotate to the first position. Thereafter, in association with rotation of the first rotary body, the moving member moves to a fourth position, in which the moving member is unable to contact the contacted part.

Abstract: A microphone-unit supporting structure comprises a microphone unit and a holder. The microphone unit includes a substantially-cylindrical microphone element, a printed circuit board fixed to a back of the microphone element, and at least two projections extending radially outward from the printed circuit board and being circumferentially spaced at such an angular interval that when one of the projections is assumed to be on a reference line for line symmetry, the other projection or projections are off the reference line. The holder includes a microphone-unit supporting portion for supporting the microphone unit. The holder has a first groove for receiving first one of the projections, and a second groove for receiving second one of the projections. The first groove is open in a backward direction. The second groove is open in a frontward direction.

Abstract: A developing device comprises: a development roller configured to rotate while carrying liquid toner which comprises a carrier liquid and toner particles contained in the carrier liquid; a cleaning blade configured to contact with the development roller to scrape off the liquid toner carried on the development roller by the rotation of the development roller; and a cleaning roller provided adjacent to the development roller and upstream from the cleaning blade with respect to a rotating direction of the development roller. In the developing device, the development roller and the cleaning roller are configured to rotate in such a direction that outer peripheral surfaces thereof move in opposite directions to each other at a contact surface where the cleaning roller contacts with the development roller.
