IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes a plurality of image bearing members, replaceable development units, replaceable toner replenishing members, toner supply units, and a control unit. The development units are each provided for a corresponding one of the plurality of image bearing members. The toner replenishing members are each provided for a corresponding one of the development units. The toner supply units are arranged between the respective toner replenishing members and the development units. The control unit causes the image forming apparatus to execute a toner supply unit cleaning mode to convey a last-used toner inside the toner supply unit into the development unit which is last used and to be replaced to empty the toner supply unit, when replacement of the development unit and the corresponding toner replenishing member is designated to use a toner of a type different from the last-used toner.

主权项

1. An image forming apparatus, comprising:
a plurality of image bearing members; replaceable development units each provided for a corresponding one of the plurality of image bearing members to render electrostatic latent images formed on the respective image bearing members visible as toner images based on image data; replaceable toner replenishing members each provided for a corresponding one of the development units to replenish toner to the respective development units; toner supply units arranged between the respective toner replenishing members and the development units; and a control unit configured to cause the image forming apparatus to execute a toner supply unit cleaning mode to convey a last-used toner inside a toner supply unit between a toner replenishing member to be replaced and a development unit to be replaced to the development unit which is last used and to be replaced to empty the toner supply unit, when replacement of the development unit and the corresponding toner replenishing member is designated to use a toner of a type different from the last-used toner.
