    Abstract: A toner container includes a toner storage unit, a container base portion including a discharge port provided on an outer surface of the container base portion, the outer surface extending in a first direction, the discharge port communicating with the toner storage unit, and a container shutter configured to be rotatable about a rotation axis extending in a direction along the first direction between a shielding position and an open position. The container base portion includes an engaging portion configured to be engaged with an engaged portion of the image forming apparatus so that rotation of the container base portion with respect to the image forming apparatus about the rotation axis is restricted. At least a part of the engaging portion of the container base portion is exposed from the container shutter in a case where the container shutter is in the shielding position.

    Abstract: An image forming apparatus includes a first unit including an image bearing member and a second unit. The second unit includes a developing roller to supply the toner to the image bearing member, a mounting portion in which the replenishing container is dismountably mounted, and an accommodating portion to accommodate the toner replenished from the replenishing container. The second unit is movable between a first position where the developing roller contacts the image bearing member and a second position where the developing roller separates from the image bearing member. When a moving direction in which the second unit moves from the first position toward the second position is defined as a separating direction, the second unit is urged in the separating direction by a force which the mounting portion receives from the replenishing container when the replenishing container is mounted to the mounting portion.

    Abstract: An image forming apparatus includes: a main body; a developing cartridge having a housing, a memory medium, a memory medium unit, a developer carrier, and a protrusion portion in the longitudinal direction of the developer carrier; and a tray having a frame, an image bearing member, a guide member provided at one end in the longitudinal direction, an electric contact portion with the memory medium, and a memory unit support portion. The guide member includes a portion which functions as a memory unit support portion, and a downstream portion located downstream of the memory unit support portion in the mounting direction of the developing cartridge. The memory unit support portion guides the protrusion portion to the downstream portion when the developing cartridge is mounted on the frame.

    Abstract: A toner container includes a toner accommodating portion, a discharge portion, a shutter, a sealing member, and a guiding portion. In a case where a direction from the toner accommodating portion toward the discharge portion in a rotational axis direction is a first direction, where a direction opposite to the first direction is a second direction, and where an end portion of the sealing member on a downstream side of the first direction is a first end portion, a downstream end portion of the guiding portion is positioned downstream of the first end portion of the sealing member with respect to the first direction. The downstream end portion of the guiding portion overlaps with the sealing member as viewed in the rotational axis direction, and includes an inclined surface inclined so as to approach the contact surface of the seal member as it goes in the second direction.
