Example implementations relate to toner particle storage. An example toner storage device includes a toner particle hopper and a heating device coupled to the hopper to heat toner particles received at the toner particle hopper to compress the toner particles.

An image forming apparatus includes an image forming portion, an intermediary transfer belt, a first mounting portion for mounting a first collecting container, a second mounting portion for mounting a second collecting container, and a feeding device including a first discharging portion and a second discharging portion. The first mounting portion and the second mounting portion are provided below the intermediary transfer belt and are disposed side by side in a widthwise direction perpendicular to a rotational axis direction of the image bearing member. As viewed in the vertical direction, each of the first mounting portion and the second mounting portion is provided at a position where at least a part of the mounting portion overlaps with the intermediary transfer belt.

An image forming apparatus includes: a drawer movable between an inner position and an outer position and supporting a first cartridge including a first photosensitive drum and a first discharge part and a second cartridge including a second photosensitive drum and a second discharge part; and a waste toner box including a first coupling part coupled with the first discharge part and a second coupling part coupled with the second discharge part, in a state where the first cartridge and the second cartridge are supported by the drawer at an inner position and the waste toner box is mounted to the apparatus main body, the waste toner box being movable between a first/second position where the first coupling part and the first discharge part are coupled/decoupled and the second coupling part and the second discharge part are coupled/decoupled.

In an example, a print apparatus comprises an intermediate transfer member to receive thermoplastic print agent from a photoconductive surface, a rotatably mounted endless cleaning surface to receive a layer of thermoplastic print agent from the intermediate transfer member and a heater, to heat the endless cleaning surface. The endless cleaning surface may be to engage with the intermediate transfer member when heated to transfer residue from the intermediate transfer member to the layer of thermoplastic print agent on the endless cleaning surface.

A device for removing toner attached to a transfer roller in an image forming apparatus is disclosed. The device includes a bar brush to contact an outer circumferential surface of the transfer roller, where the bar brush extends along a part of a longitudinal length of the transfer roller. The device includes an elongated cleaning member to contact the outer circumferential surface of the transfer roller, where the elongated cleaning member extends along the longitudinal length, entirely, of the transfer roller.

An image forming apparatus includes an image holding unit that holds an image that is formed of a developer, the image being intended to be transferred onto a medium, and an image that is not intended to be transferred onto a medium, a transfer unit that transfers the image that is intended to be transferred onto a medium onto a medium, a removing unit that removes the image that is not intended to be transferred onto a medium from the image holding unit, and a forming unit that forms the image that is not intended to be transferred onto a medium onto the image holding unit by using a developer and that has a first forming mode for a first medium and a second forming mode for a second medium that has a transfer sensitivity lower than a transfer sensitivity of the first medium, the forming unit being configured to use a larger amount of the developer in formation of the image that is not intended to be transferred onto a medium in the first forming mode than in the second forming mode.

A belt running device includes a plurality of rollers, a belt, a guide, a regulating member, and an abutting member. The belt is wound around the plurality of rollers and configured to rotate. The guide is provided at an end of an inner peripheral surface of the belt. The regulating member is provided at an end of at least one roller of the plurality of rollers in the axial direction of the at least one roller and configured to contact the guide and regulate a movement of the belt in the axial direction of the at least one roller. The abutting member is configured to contact an outer peripheral surface of the belt to press the belt inward in a vicinity of a contact start point at which the guide and the regulating member start to contact when the belt runs.

An image forming apparatus including a revolving member, a first-transfer member, a second-transfer member that transfers the toner image on the revolving member onto a recording medium, a removing member downstream of the second-transfer member to remove a deposit on the revolving member, a fixing device that generates heat and that fixes the toner image transferred on the recording medium, a generating member that causes air to flow from the fixing device toward the revolving member, and an executing unit that executes a removal mode including causing the fixing device to generate heat, causing the generating member to operate, causing the revolving member to operate, causing the first-transfer member to operate so as to transfer a cleaning image as a toner image onto the revolving member, and causing the removing member to remove the cleaning image from the revolving member without transferring the cleaning image onto the recording medium.
