摘要： A powder transport apparatus includes a housing and first and second transport members. The housing includes first and second transport paths that are separated by a partition wall extending in one direction. The first and second transport paths are connected by first and second connection ports. The first and second connection ports are separated in the one direction with the partition wall interposed therebetween. The first transport member is provided in the first transport path. The first transport member transports powder. The second transport member is provided in the second transport path. The second transport member transports the powder. A transport force of the second transport member at a portion of the second transport member where the second transport member faces the first connection port is smaller than a transport force of the second transport member at a portion where the second transport member faces the partition wall.

摘要： An image forming apparatus includes an accommodation container, a storage medium, and a controller. The accommodation container includes a rotational portion and outflow portion. The rotational portion accommodates a developer therein and has a helical-shaped transport section formed in an inner surface thereof. The outflow portion rotatably supports the rotational portion and has an outflow port through which the developer transported during rotation of the rotational portion flows out. The storage medium stores use state information of the developer accommodated in the rotational portion. The controller controls a driving source which drives the rotational portion. When a use state of the accommodation container for the developer is a use state which is set in advance, the controller intermittently drives the rotational portion by performing driving at a rotation angle of (n+1/2)π±18 degrees or less than 90 degrees and stopping.

摘要： A developing device includes a developer container, a magnet member, a developer carrier including a rotary member, and a developer transport member, the magnet member including an attracting magnet pole that attracts a developer on the rotary member and a separation magnet pole that releases the developer. The attracting magnet pole is disposed upstream of a line segment connecting the centers of rotation of the rotary member and the transport member in a rotation direction of the rotary member. The magnetic force of the separation magnet pole is about 35 mT or more and about 45 mT or less, and the magnetic force of the attracting magnet pole is about 38 mT or more and about 54 mT or less. The angle formed by the magnet poles with respect to the center of rotation of the rotary member is about 98 degrees or more and about 117 degrees or less.

摘要： An image forming apparatus includes: an image carrier that carries an image; a transport-path forming part that forms a transport path for developer used to develop the image carried by the image carrier; a transport member that transports the developer in the transport path; and a concentration detector that detects toner concentration in the developer in the transport path. The transport path includes a first portion and a second portion. Difference in sectional area between the second portion and the transport member in a direction intersecting a direction in which the developer is transported is smaller than difference in sectional area between the first portion and the transport member. The second portion is located downstream of the first portion in the direction in which the developer is transported. The concentration detector is disposed in the second position of the transport path.

摘要： A developer transport device includes a transport path through which a developer is transported from a developer container to a developing device; an inlet portion that is disposed at an upstream end of the transport path in a developer transport direction and into which the developer falls freely from an outlet opening of the developer container; a transport member that is disposed in the transport path and that transports the developer by rotating; and a rotation control unit that causes, if the transport member has not been driven for a predetermined period, the transport member to rotate in a backward direction that is opposite to a forward direction in which the transport member rotates when supplying the developer to the developing device.

摘要： A powder container device includes a powder container that contains powder and has an opening at one end, the powder container being installed in a substantially horizontal orientation and having a projection on an inner peripheral surface of the powder container, the projection transporting the powder toward the opening when the powder container rotates; and a lid member that covers the opening and has an outlet through which the powder flows, the lid member being held in a non-rotatable manner. The powder container device does not have a structure for scooping the powder, which has been transported by the rotation of the powder container, toward a rotational axis, and discharges the powder through the outlet.
