Image forming apparatus

An image forming apparatus comprising:

• a developing unit including a developing roller and a storage frame having a storage portion configured to store toner to be supplied to the developing roller;
• a toner cartridge configured to store toner;
• a drive source;
• a moving member configured to be moved in a movement direction by a driving force of the drive source;
• a drive transmission mechanism configured to transmit the driving force from the drive source to the moving member,
• wherein the moving member includes a first force receiving portion configured to receive the driving force from the drive transmission mechanism, and a second force receiving portion disposed at a position away from the first force receiving portion in a direction intersecting with the movement direction and configured to receive the driving force from the drive transmission mechanism,
• wherein the drive transmission mechanism is configured to transmit a force that the drive transmission mechanism has received from the first force receiving portion of the moving member to the second force receiving portion, and to transmit a force that the drive transmission mechanism has received from the second force receiving portion of the moving member to the first force receiving portion,
• wherein the toner cartridge is detachably attached to the moving member, and
• wherein the moving member is movable in the movement direction between a first position in which detachment of the toner cartridge from the moving member is allowed and a second position in which supply of the toner from the toner cartridge to the developing unit is allowed;
• and
• a rotary which is rotatable and which includes the developing unit,
• wherein the second force receiving portion is disposed at a position away from the first force receiving portion in a rotational axis direction of the rotary.
