Abstract
An image forming apparatus configured to output first information for urging arrangement of delivery of a container of toner based on a detection result of a toner sensor, wherein when a first period from a detection of toner to an arrival at a first predetermined value of an accumulation value of a count portion is longer than a predetermined period, image formation is inhibited based on the accumulation value with outputting second information for urging replacement of the container, and when the first period is shorter than the predetermined period, the image formation is continued during the predetermined period until a detection result of a load sensor reaches a second predetermined value.
Claims4
An image forming apparatus, comprising:
- an image forming portion configured to form an image;
- a container configured to contain toner collected from the image forming portion;
- a conveyance member, which is provided inside of the container so as to be rotatable, and is configured to convey the toner contained in the inside;
- a toner sensor configured to detect toner presence or toner absence at a detection portion provided in the inside of the container and on downstream of the conveyance member in a conveyance direction;
- a count portion configured to count a value correlated to a toner amount collected into the container;
- a controller configured to output first information for urging arrangement of delivery of the container based on a detection result of the toner sensor;
- and
- a load sensor configured to detect a rotation load of the conveyance member,
- wherein, when a first period from when the toner sensor detects the toner presence to when an accumulation value counted by the count portion reaches a first predetermined value is longer than a predetermined period, the controller outputs second information for urging replacement of the container and inhibits image formation based on the accumulation value counted by the count portion, and
- wherein, when the first period is shorter than the predetermined period, the controller is allowed to continue an image forming operation during the predetermined period until a detection result of the load sensor reaches a second predetermined value.
An image forming apparatus, comprising:
- an image forming portion configured to form an image;
- a container configured to contain toner collected from the image forming portion;
- a conveyance member, which is provided inside of the container so as to be rotatable, and is configured to convey the toner contained in the inside;
- a toner sensor configured to detect toner presence or toner absence at a detection portion provided in the inside of the container and on downstream of the conveyance member in a conveyance direction;
- a count portion configured to count a value correlated to a toner amount collected into the container;
- a controller configured to output first information for urging arrangement of delivery of the container based on a detection result of the toner sensor;
- and
- a load sensor configured to detect a rotation load of the conveyance member,
- wherein the controller outputs second information for urging replacement of the container and inhibits image formation based on the accumulation value counted by the count portion in a case in which an operation of forming images on a predetermined number of sheets per one day, in which a toner consumption amount of an image per one sheet is a first predetermined amount, has been repeated, and
- wherein the controller outputs the second information and inhibits the image formation based on a detection result of the load sensor in a case in which an operation of forming images on the predetermined number of sheets per one day, in which a toner consumption amount of an image per one sheet is a second predetermined amount larger than the first predetermined amount, has been repeated.
