摘要： An image forming apparatus includes a charging bias output device, a developing bias output device, a transfer bias output device, and a controller. The controller controls the transfer bias output device to supply a transfer bias from a time at which a first position of a photosensitive member arrives at a transfer position after the charging bias output device starts supplying a charging bias. An initial value of the transfer bias is controlled to be smaller than a normal set value for a predetermined time period which is a time after the transfer bias starts to be supplied and within a time corresponding to a rise time during which a surface potential of the photosensitive member reaches a predetermined potential after the charging bias starts to be output. The first position of the photosensitive member is a position at which the charging device starts charging the photosensitive member.

摘要： A lubricant applying unit has a residual-toner collection rate X of 50% when the lubricant applying unit has not been used. The collection rate X is obtained by X=(Ta−Tb)/Ta×100, where Ta is weight per unit area of the residual toner on an area of the image carrier that has not come into contact with the lubricant applying unit, and Tb is weight per unit area of the residual toner on an area of the image carrier that has come into contact with the lubricant applying unit.

摘要： An image forming apparatus includes a photoconductive element including a conductive support rotatably supported and a charge injection layer and a surface protection layer sequentially laminated on the conductive support. A charger includes a conductive body for injecting, when a preselected voltage is applied thereto, a charge in the charge injection layer in contact with the surface protection layer. A writing unit exposes the charged surface of the photoconductive element imagewise to thereby locally vary the potential deposited on the photoconductive element and electrostatically form a latent image. A developing unit develops the latent image to thereby produce a corresponding toner image. The toner image is transferred from the photoconductive element to a recording medium. Assuming that the charge injection layer has a thickness of D micrometers, and that the potential deposited on the surface of the photoconductive element by the conductive member is V volts in absolute value, then a ratio V/D is confined in a preselected range that does not contaminate the background of the photoconductive element.

摘要： A collection container for collecting and containing waste toner includes a leveling member, a detector, and at least one inlet. The leveling member levels the waste toner contained in the collection container. The detector detects an amount of the waste toner contained in the collection container.
