摘要： An image forming apparatus includes an image carrying member, a developing device, a cleaning unit and a processor. The developing device performs development with a developer containing a toner and a lubricant. The processor obtains information on a lubricant amount in the developing device; obtains, with respect to each section formed by dividing a surface of the image carrying member in a rotating shaft direction of the image carrying member, a partial coverage from electrostatic latent image writing information for a predetermined period about the section; sets, for the section having the partial coverage of a predetermined value or less, a developer supply amount for a patch to be formed outside an image forming region on the image carrying member, based on the above information; and causes the developing device to supply the set developer supply amount so that the patch is formed.

摘要： The present wet development device includes a developer carrying member, a supply member that supplies a liquid developer to the developer carrying member, a charger that charges the liquid developer on the developer carrying member, a cleaner that removes the liquid developer on the developer carrying member, and a bias applying member that applies alternating bias in contact with the developer carrying member before removing by the cleaner. In a direction in alignment with an axis of rotation of the developer carrying member, a range to which the alternating bias is applied by the bias applying, member is located within a range in which the liquid developer is supplied onto the developer carrying member.

摘要： An image forming apparatus includes an image carrying member, a developing device, a cleaning unit and a processor. The developing device performs development with a developer containing a toner and a lubricant. The processor obtains information on a lubricant amount in the developing device; obtains, with respect to each section formed by dividing a surface of the image carrying member in a rotating shaft direction of the image carrying member, a partial coverage from electrostatic latent image writing information for a predetermined period about the section; sets, for the section having the partial coverage of a predetermined value or less, a developer supply amount for a patch to be formed outside an image forming region on the image carrying member, based on the above information; and causes the developing device to supply the set developer supply amount so that the patch is formed.
