    摘要： An image formation apparatus includes a toner bottle, a sub hopper configured to temporarily store toner supplied from the toner bottle, a development apparatus configured to receive supply of the toner from the sub hopper, a first detector configured to detect a remaining amount of toner in the toner bottle, a second detector configured to detect an empty space for toner in the sub hopper, and a controller configured to have the toner supplied from the toner bottle to the sub hopper each time the empty space in the sub hopper exceeds a threshold value Th1. When the remaining amount of toner in the toner bottle is smaller than a threshold value ThA, the controller lowers the threshold value Th1 to a threshold value Th2.

    摘要： An image forming apparatus includes a development device, a toner container which includes data indicating whether the toner container is an installation toner container or a replacement toner container and a memory storing the value of a remaining amount related item, a supply portion, a read/write portion which performs the reading and writing of the memory and a control portion which reduces the present value of the remaining amount related item according to the number of sheets printed. When in a state where installation has already been performed, the installation toner container is attached, the control portion stores, in the memory, a value based on the remaining amount of toner before the installation.

    摘要： A development device includes a development housing, a first developer conveyance member, a developer bearer, and a developer amount detector to detect an amount of developer in the development housing. The developer amount detector includes a light-emitting element, a right-receiving element, a first light guide including a first end from which light enters and a second end disposed inside the development housing, and a second light guide including a first end positioned inside the development housing across a predetermined distance from the second end of the first light guide and a second end from which the light exits. The second end of the first light guide and the first end of the second light guide are arranged in an axial direction of the first developer conveyance member with a light transmission path therebetween partly inside a locus of rotation of the first developer conveyance member.

    摘要： An image forming apparatus includes an image bearing member for bearing a latent image, a developer carrying member for developing the latent image with a developer, a developer accommodating portion for accommodating the developer, and a detecting device including a light emitting element and a light receiving element for detecting a remaining developer amount in the developer accommodating portion. In addition, a stirring member stirs the developer by rotating in the developer accommodating portion. The stirring member is rotated in a first period in which the stirring member crosses an optical path of light from the light emitting element toward the light receiving element and a second period in which the stirring member does not cross the optical path of the light. The stirring member is rotated at a first rotational speed in the first period and is rotated at a second rotational speed in the second period higher than the first rotational speed, and wherein the first period and the second period are included in one rotation of the stirring member.
