A mechanism that enables developer replenishment by a simpler structure and a mechanism that enables more user-friendly developer replenishment are provided. An attachment port to which a developer supply bottle containing a developer stored therein is detachably attachable is disposed in an interior of an image forming apparatus. The developer supply bottle can be attached when the cover is in an open state. According to this image forming apparatus, when the developer supply bottle is attached to the attachment port, the developer inside the developer supply bottle moves into a developer housing chamber by its own weight.

Image forming apparatus with simplified developer replenishment structure and that is user-friendly

An image forming apparatus includes a developer container to and from which a replenishment container is attachable and detachable and which includes an accommodating portion that accommodates developer and a replenishment port, an agitation member, an opening/closing member configured to be movable between a closed position and an open position, a drive source for driving the agitation member, and a control portion configured to control the drive source. The apparatus is configured such that image formation is not possible when the opening/closing member is at the open position, and the agitation member is capable of driving in a case where the opening/closing member is at the open position.

Image forming apparatus

An image forming apparatus includes a developer container having an accommodating portion to accommodate developer, and a replenishment port for replenishing the accommodating portion with developer from an attachable replenishment container. A transfer portion transfers the developer image on an image bearing member onto a recording material, a supporting tray supports the recording material, and a discharge portion discharges the recording material on the supporting surface. The supporting tray has an opening portion opening with the replenishment port being exposed through the supporting surface, wherein an opening/closing member is movable between a closed position where it covers the replenishment port and serves as a part of the supporting surface and an open position where the replenishment port is exposed. Movement of the opening/closing member to the closed position is hindered by the replenishment container in a state it is attached to the developer container.

Image forming apparatus having toner replenishment

An image forming apparatus includes a developer container to and from which a replenishment container is attachable and detachable, the developer container including an accommodating portion, and a supporting portion, wherein the developer container includes a projection portion that is provided at one end portion thereof in the rotation axis direction of the developer bearing member and projects toward the supporting portion more than a center portion of the developer container in a crossing direction crossing the rotation axis direction, the projection portion communicates with the accommodating portion and includes, at a distal end portion thereof, an attachment portion configured such that the replenishment container is attachable thereto in a state of being exposed to the outside of the apparatus, and a replenishment port for replenishing the accommodating portion with developer from the replenishment container is defined in the attachment portion.

Image forming apparatus having an opening/closing member that is prevented from closing when a replenishment container is attached to a process unit

An apparatus includes a developer container to and from which a replenishment container is attachable and detachable and which includes an accommodating portion and a replenishment port, a transfer portion configured to transfer a developer image on an image bearing member onto a recording material, a supporting tray including a supporting surface configured to support the recording material thereon, and a discharge portion configured to discharge the recording material, onto which the developer image has been transferred, on the supporting surface, wherein the supporting surface has an opening portion opening such that the replenishment port is exposed through the supporting surface, and wherein an opening/closing member configured to be movable between a closed position where the opening/closing member covers the replenishment port and serves as a part of the supporting surface and an open position where the replenishment port is exposed is provided.

An image forming apparatus includes: a detection unit configured to detect an amount of developer stored in a developing container and to output remaining amount information; and a control unit configured to perform control, during a replenishment of the developer to the developing container using a replenishment container, to cause a display unit to display a message related to the replenishment. When the replenishment is instructed, the control unit is further configured to perform a first control during the replenishment in a case where the remaining amount information indicates a first remaining amount, and configured to perform a second control different from the first control during the replenishment in a case where the remaining amount information indicates a second remaining amount greater than the first remaining amount.

Image forming apparatus and developer replenishment thereof

An image forming apparatus includes a developer container to and from which the replenishment container is attachable and detachable and which includes an accommodating portion that accommodates developer and a replenishment port, an agitation member, an opening/closing member configured to be movable between a closed position and an open position, a drive source for driving the agitation member, and a control portion configured to control the drive source. The apparatus is configured such that image formation is not possible when the opening/closing member is at the open position, and the agitation member is capable of driving in a case where the opening/closing member is at the open position.

A recording method includes a step of applying a first ink to a recording medium; and a step of recording an image on the recording medium by applying a second ink so that the second ink at least partially overlaps a region to which the first ink has been applied. The first ink is an aqueous ink containing a silver particle. The second ink is an aqueous ink containing a coloring material. The recording medium has an ink receiving layer that contains a halide ion selected from the group consisting of a bromide ion and an iodide ion. The ink receiving layer has a halide ion content (mmol/m) of 0.1 mmol/mor more to 0.8 mmol/mor less.

Recording method, recording apparatus and recorded matter

An ink jet printing method includes printing an image on a printing medium including a transparent substrate and an ink-receiving layer on one side of the transparent substrate by applying a first ink and a second ink onto the surface of the ink-receiving layer of the printing medium in such a manner that the first ink and the second ink are at least partially superposed one on the other. The first ink is an aqueous ink containing silver particles, and the second ink is an aqueous ink containing a dye. The particle size at 50% in the cumulative volume distribution of the silver particles is larger than the average pore size of the ink-receiving layer.
