摘要： [Problem] To provide further development of a photosensitive member unit.
[Solution]
A photosensitive member unit detachably mountable to a main assembly of an image forming apparatus, the image forming apparatus including a first main assembly side helical gear portion and a second main assembly side helical gear portion which are coaxially rotatable, the photosensitive member unit includes a photosensitive member rotatable about a rotational axis thereof; a first unit side helical gear portion for meshing engagement with the first main assembly side helical gear portion; and a second unit side helical gear portion for meshing engagement with the second main assembly side helical gear portion, wherein a twisting direction of a tooth of the second unit side helical gear portion is the same as the twisting direction of a tooth of first unit side helical gear portion, wherein a helix angle of the tooth of the second unit side helical gear portion is larger than a helix angle of the tooth of the first unit side helical gear portion, and wherein the first unit side helical gear portion and the second unit side helical gear portion are rotatable in a state in which the first unit side helical gear portion is in meshing engagement with the first main assembly side helical gear portion, and the second unit side helical gear portion is in meshing engagement with the second main assembly side helical gear portion.

摘要： The present invention relates to a toner cartridge and an image forming apparatus comprising such a cartridge. This cartridge comprises a casing including an accommodation chamber accommodating toner and a discharge opening capable of discharging the toner; a pump configured to discharge the toner through the discharge opening by using air; and a coupling member configured to receive a rotational force for driving the pump, wherein as viewed along an axis of the coupling member in a state that the toner cartridge takes an attitude in which the discharge opening directed downward, the discharge opening is on a first side with respect to a center of the pump in a horizontal direction, and an axis of the coupling member is on a second side which is opposite from the first side, with respect to the center of the pump in the horizontal direction.

摘要： A toner cartridge includes a casing, a feeding member and a pump. the casing includes a toner accommodation chamber accommodating toner, and a toner discharging chamber having a discharge opening for discharging the toner, and a communication port for fluid communication between the toner accommodation chamber and the toner discharging chamber. A part of the feeding member is provided inside the communication port. When a minimum cross-sectional area of the communication port in a plane perpendicular to a toner feeding direction of the feeding member is Asmin, the toner discharging chamber has a cross-sectional area Bs larger than Asmin, and the toner accommodation chamber has a cross-sectional area Cs larger than Asmin.
