Abstract

An image forming apparatus includes an image bearing member on which an electrostatic latent image is formable, and a developing device including a developer carrying member, a container, and a supply roller. When the developing device including the developer carrying member, to which a lubricant different from the developer is applied, is used for the first time, a first initial operation of transferring the lubricant from the developer carrying member to the image bearing member together with the developer is performed. The image forming apparatus further includes a storage unit configured to store a suspension state when suspension is detected before the initial operation completes, and a controller configured to execute a second initial operation as an operation of resuming the suspended first initial operation on the basis of the stored suspension state.

Dependent claims

An image forming apparatus comprising:

an image bearing member on which an electrostatic latent image is formable;
and
a developing device including (1) a developer carrying member for carrying a developer and developing the electrostatic latent image, (2) a container storing the developer, and (3) a supply roller supplying the developer to the developer carrying member,
wherein when the developing device including the developer carrying member, to which a lubricant different from the developer is applied, is used for the first time, a first initial operation of transferring the lubricant from the developer carrying member to the image bearing member together with the developer is performed, and
wherein the image forming apparatus further comprises:
a storage unit configured to store a suspension state when suspension is detected before the first initial operation is completed;
and
a controller configured to execute a second initial operation as an operation of resuming the suspended first initial operation on the basis of the stored suspension state.
