A developing device includes a developer bearer and a stirring conveyor. The stirring conveyor includes a first conveying chamber including a conveying member and a second conveying chamber to receive the developer from an end of the first conveying chamber. The conveying member includes a forward winding blade, a reverse winding blade, and a shaft portion on which the forward winding blade and the reverse winding blade are mounted with a space therebetween. A circumferential phase of the conveying member at a start position of the reverse winding blade is different from a circumferential phase of the conveying member at an end position of the forward winding blade. The conveying member is disposed in the first conveying chamber so that the space is opposite a portion at which the second conveying chamber receives the developer from the end of the first conveying chamber.

A developing device includes a developer container, a developing roller, and a doctor member. The developer container contains a developer including a toner and a developer. The developing roller includes a developing sleeve bearing the developer, a magnet roller in the developing sleeve. The doctor member includes a regulating portion regulating an amount of the developer home on the developing sleeve to be a predetermined amount. The regulating portion is disposed with a first distance from the developing sleeve. The developing sleeve is disposed with a second distance from an image hearer, and when the developing sleeve bearing the predetermined amount of developer passes a vicinity of the image bearer, a value obtained by dividing the predetermined amount by the second distance is less than a threshold of occurrence of adherence of the developer to the developing sleeve.

Developing device regulates an amount of developer on a developing sleeve

A toner container includes a cylindrical container body having a head with an opening in the head, a cap into which the head of the container body is inserted, and a sheet member attached inside the cap. The cylindrical container body rotates around a rotation axis extending in a longitudinal direction of the container body to transport toner contained in the container body toward the opening. The cap has a toner outlet through which the toner discharged from the opening is discharged outside the toner container. The sheet member includes a first elastic-deformation portion that is elastically deformable and located near the toner outlet, and a second elastic-deformation portion that is elastically deformable and located in the container body and near the opening.

Toner container, toner supply device, and image forming apparatus including a sheet member with two portions to move toner

A developer conveyor includes a shaft; a first blade helically wound around the shaft in a first direction, a second blade disposed away from an end of the first blade with a gap in a longitudinal axial direction of the developer conveyor and helically wound around the shaft in a second direction opposite the first direction, and a third blade helically wound around the shaft in the first direction at least at a position where the gap is formed.

Developer conveyor having three blades

A communication device, which performs wireless communication according to an adaptive modulation scheme, includes a modulator that modulates data to be transmitted to generate a transmission signal, and a transmission power control unit that controls a transmission power of the transmission signal, wherein, when the modulation level increases according to the adaptive modulation scheme, the transmission power control unit starts control of the transmission power before the modulator increases the modulation level.

Communication device and communication method

A developing device includes a developer container to contain developer including toner and magnetic carrier, the developer container; a developer bearer to carry, by rotation, the developer to a developing range facing a latent image bearer; a communication opening in a wall defining the developer container; a toner conveyance passage connected to the communication opening; and a cylindrical magnet having a magnetic pole arrangement parallel to an axis of the cylindrical magnet. The cylindrical magnet is disposed to enclose a space overlapping with the communication opening on a cross section perpendicular to the axis of the cylindrical magnet.

An image forming apparatus includes a latent image bearer having a shaft to rotate in a normal direction for image formation and a reverse direction, a charging device, a latent image forming device, a developing device including a developer bearer having a shaft, a driving source, a drive transmission device to transmit a driving force from the driving source to the shaft of the latent image bearer and the shaft of the developer bearer. The developer bearer rotates in a predetermined direction during image formation and transports developer including toner to a developing range facing the latent image bearer, thereby developing the latent image on the latent image bearer. The drive transmission device is configured to inhibit transmission of the driving force to the shaft of the developer bearer when the latent image bearer rotates in the reverse direction.

A developing device includes a casing having an opening, the casing to contain developer, and a developer bearer including a magnetized range to cause developer to stand on end on a surface of the developer bearer and an end range outside the magnetized range in a longitudinal direction of the developer bearer. The developer bearer is disposed in the casing and partly exposed from the opening with a casing gap secured between the surface of the developer bearer and an inner face of the casing. The developer bearer generates, by rotation, sucked-in airflow to collect a floating toner from the opening into the casing, and the casing gap is smaller in the end range than the magnetized range.
