  • Patent number: 11467514
    Abstract: An apparatus includes an image bearing member, a developer container having a replenishment port, a developer bearing member, a detection portion configured to output remainder amount information corresponding to the amount of developer accommodated in the developer container, a notification portion capable of notifying a first state, and a second state, and a control portion. The maximum amount of the developer that the developer container is capable of accommodating is larger than a value obtained by adding the amount of the developer accommodated in a replenishment container containing the developer for replenishment to the first amount, and wherein notification of the second state corresponds to notification of a case where the amount of the developer remaining in the developer container is larger than a case where the amount of the developer remaining in the developer container is the smallest.

  • Patent number: 10039674
    Abstract: In a conveyance device, first and second travel members that hold pads are arranged alternately and travel along the outer peripheral surface of a stationary drum in conjunction with the rotation of a drive member. One or both of the first and second travel members have a rotatably supported shaft member having an engaging section that engages with a guide section formed in the outer peripheral surface of the stationary drum. The rotation of the shaft member is transmitted to the pads and the pads rotate. When conveyance articles are released from pads that have received conveyance articles having the same orientation, the orientation of conveyance articles released from first pads held by the first travel member is different from the orientation of the conveyance articles released from the second pads held by the second travel member.

  • Patent number: 9895821
    Abstract: In a web cutting device, a web held by pads has a section between mutually adjacent pads that is sandwiched between an anvil and a blade edge of a cutter and cut. A stop member is fixed in a rotating member. The cutter is biased by a biasing member and comes in contact with the stop member. The stop member obstructs travel by the cutter towards the outside in the radial direction of the rotating member, when the cutter comes in contact with the stop member. The biasing member biases the cutter to the outside in the radial direction of the rotating member and causes the cutter to come in contact with the stop member, by using a predetermined biasing force, and allows the cutter to retreat when the reaction force acting on the cutter is greater than the predetermined biasing force.
