Abstract
Official abstract text for this publication.
An image forming apparatus includes a charger, a charge eliminator, and a controller. The charger charges a surface of an image carrier. The charge eliminator eliminates residual charge from the surface of the image carrier charged by the charger. The controller performs control to reduce a level of charge elimination performed by the charge eliminator during a third period compared to a level of charge elimination performed by the charge eliminator during a second period in which an image for determining an image-forming condition is formed. The third period is a period other than the second period within a first period that is a period, other than a period of normal image formation, during which the surface of the image carrier is charged by the charger.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: a charger that charges a surface of an image carrier; a charge eliminator that eliminates residual charge from the surface of the image carrier charged by the charger; and a controller that performs control to reduce a level of charge elimination performed by the charge eliminator during a third period compared to a level of charge elimination performed by the charge eliminator during a second period in which an image for determining an image-forming condition is formed, the third period being a period other than the second period within a first period that is a period, other than a period of normal image formation, during which the surface of the image carrier is charged by the charger. 2. The image forming apparatus according to claim 1 , wherein the controller further performs control to reduce a voltage applied to the charger during the third period compared to a voltage applied to the charger during the second period while the charger charges the surface of the image carrier. 3. The image forming apparatus according to claim 1 , wherein the controller performs control to reduce the level of charge elimination by turning off the charge elimination performed by the charge eliminator. 4. The image forming apparatus according to claim 2 , wherein the controller performs control to reduce the level of charge elimination by turning off the charge elimination performed by the charge eliminator. 5. An image forming method comprising: charging a surface of an image carrier; eliminating residual charge from the charged surface of the image carrier; and performing control to reduce a level of charge elimination performed during a third period compared to a level of charge elimination performed during a second period in which an image for determining an image-forming condition is formed, the third period being a period other than the second period within a first period that is a period, other than a period of normal image formation, during which the surface of the image carrier is charged. 6. A non-transitory computer readable medium storing a program causing a computer to execute a process for image formation, the process comprising: charging a surface of an image carrier; eliminating residual charge from the charged surface of the image carrier; and performing control to reduce a level of charge elimination performed during a third period compared to a level of charge elimination performed during a second period in which an image for determining an image-forming condition is formed, the third period being a period other than the second period within a first period that is a period, other than a period of normal image formation, during which the surface of the image carrier is charged.
