Abstract: The invention provides an electroconductive roll having at least a surface layer forming an outer peripheral surface of the electroconductive roll. The surface layer contains projections and recesses. The projections contain a plurality of particles. A ratio of an area occupied by particles existing in a cross-section of a projection to an entire area of the cross-section of the projection is larger than a ratio of an area occupied by particles existing in a cross-section of a recess to an entire area of the cross-section of the recess. The invention further provides a process cartridge having a charging roll which is the electroconductive roll and/or a transfer roll which is the electroconductive roll. The invention further provides an image forming apparatus having a charging unit containing the electroconductive roll and/or a transfer unit containing the electroconductive roll.

Abstract: An ozone generating apparatus is provided which includes a pair of electrodes for producing a discharge by the application of an ac voltage therebetween, and at least one dielectric provided between the pair of electrodes. A source gas containing oxygen is provided into a discharge space in which the discharge is produced to generate ozone by the action of the discharge. A surface lying between at least one of the pair of electrodes and the discharge space and in contact with the discharge has a surface resistivity of 104 Ω to 1011 Ω. The source gas provided into the discharge space includes ultrapure oxygen having a purity of not less than 99.9%.
