According to an image forming device of the present disclosure, a required replenishment amount is calculated based on a printing rate derived from image data, and toner is replenished to a development device by a toner replenishment device for a required replenishment time in accordance with the required replenishment amount. Then, a time difference obtained by subtracting a printing time per sheet from the required replenishment time is accumulated, and a determination regarding forcible replenishment of the toner is made based on a comparison between an accumulated required replenishment time and an accumulated required replenishment time threshold value.

An image forming apparatus includes an apparatus body, a process unit having an image bearing member, a developer container configured to accommodate toner, a developing portion to develop an electrostatic latent image formed on the image bearing member into a toner image by using the toner accommodated in the developer container; and a replenishment port configured to allow replenishment of toner from the replenishment container, and a display portion. A controller notifies a user of information related to a toner amount by using the display portion in a case where it is determined that a lifetime of the process unit will expire before a sum of toner accommodated in the developer container and toner accommodated in the replenishment container is consumed, wherein the information related to a toner amount is a notification about toner, to be supplied from the replenishment container, which goes to waste.

This utility model belongs to the field of refillable ink cartridge technology, and particularly relates to a refillable ink cartridge that facilitates toner refilling. It includes a refillable ink cartridge body, with a limiting block fixedly connected to one end of the body. An installation spring is fixedly connected to the end of the body away from the limiting block. A toner refilling seat is installed at the top of the body. A connection port is provided on the inner wall of the refilling seat, and a sealing plug is fitted into the inner wall of the connection port. A sealing ring is provided at the connection between the sealing plug and the connection port. By using the sealing plug, the operator injects toner into the refillable ink cartridge body through the connection port on the inner wall of the refilling seat. Then, the operator fits the sealing plug into the connection port on the inner wall of the refilling seat. The sealing ring improves the sealing performance of the sealing plug. Simultaneously, the pressure ring and rubber seat facilitate a stable engagement between the sealing plug and the refilling seat, preventing the sealing plug from falling off and causing a decrease in its sealing performance.

To provide an image forming apparatus and a toner supply control method in the image forming apparatus configured to supply two kinds of toner with one driving source, and to supply the two kinds of toner with good balance.SOLUTION: According to an image forming apparatus (10), when at least one of cumulative required supply times (Tz[X]) of two kinds of toner becomes a threshold (Ta) for toner supply or more, supply of one toner (α) is performed. The supply of the one toner (α) is performed over a cumulative required supply time (Tz[α]) of the one toner (α) and with a continuous supply allowed time Ton as an upper limit. Subsequently, supply of the other toner (β) is performed according to a cumulative required supply time (Tz[β]) of the other toner (β) and the current cumulative required supply time (Tz[α]) of the one toner (α), or the supply of the one toner (α) is resumed, or supply of both kinds of toner (α and β) is brought into a stopped state.SELECTED DRAWING: Figure 5

This invention provides a toner refiller for copier ink cartridges, belonging to the field of toner refilling technology. It includes a refiller body and a toner outlet tube installed at the toner outlet of the refiller body. It also includes a protective component, which comprises a movable tube movably inserted into the bottom of the toner outlet tube. A guide cover, funnel-shaped, is fitted over the surface of the movable tube, and an inner shell is fitted over the outer side of the guide cover. By incorporating the protective component and a suction device, during operation, the outer shell moves downwards, covering the top of the ink cartridge. A sealing plate adheres to the second through-hole. The suction device is activated, creating negative pressure at one through-hole. The dispersed toner is guided by the guide cover, allowing it to smoothly enter the collection cavity through the first through-hole, preventing toner from scattering in the air and protecting the operator's health. After refilling, the outer shell moves upwards, and the sealing plate adheres to the first through-hole, preventing toner from escaping. The toner is collected in the collection cavity, achieving toner collection and preventing toner waste.

This utility model relates to the field of toner cartridge technology, specifically a toner cartridge with auxiliary toner refilling capability. It includes a toner cartridge body for supplying toner, a feed pipe for feeding is connected through the upper part of the inner wall of the toner cartridge body, and a screw cap for sealing is threaded onto the upper part of the feed pipe. The toner cartridge body contains a feeding mechanism for auxiliary toner feeding and a dehumidification mechanism for dehumidifying the toner. The feeding mechanism includes a housing connected to the inner wall of the toner cartridge body for protecting bevel gears a and b. An auger for feeding is connected through a damping bearing to the upper part of the inner wall of the housing and is disposed inside the feed pipe. This toner cartridge with auxiliary toner refilling assists in refilling by inserting the toner bottle into the feed pipe and then continuously squeezing the arc-shaped toothed plate to drive the auger to rotate, preventing blockage during toner refilling. A desiccant absorbs moisture from the toner inside the toner cartridge body, preventing clumping.

To provide an image forming apparatus that can reduce the frequency to replace a waste toner container.SOLUTION: An image forming apparatus executes, at a specific timing, an image forming operation without toner supply that is image forming control while inhibiting toner supply to form an image to be transferred to a transfer paper that is a recording material, with toner supply performed by a toner supply device that is toner supply means being stopped. The image forming operation without toner supply performs adjustment of an image forming condition for setting a developing bias, an electrification bias, and the amount of exposure on the basis of a detection result from a toner concentration sensor that is toner concentration detection means (S24). When the detection result from the toner concentration sensor becomes equal to or less than a prescribed toner concentration (NO in S20, S29), or when one of the electrification bias, the developing bias, and the amount of exposure becomes equal to or more than an upper limit (NO in S23), the image forming apparatus ends the image forming operation without toner supply and resumes toner supply control (S21, S24, S30).SELECTED DRAWING: Figure 8
